Photographic materials with ballasted, alkali cleavable azo dyes

Abstract

Azo dye-providing compounds and photographic materials containing such compounds are described. The present compounds, as a function of photographic processing under alkaline conditions, provide a dye substance having a mobility different than that of the compound.

Description

This invention relates to the art of photography and more particularly, to color diffusion transfer photography employing cyan dye-providing compounds.

Color diffusion transfer processes generally involve the use of a photographic element comprising a support, at least one silver halide emulsion layer and an image dye-providing material which is contained in or contiguous said layer. The image dye-providing material typically can be thought of as having the structure Car-Col wherein Col is a colorant such as a dye or a dye precursor and Car is an associated carrier or monitoring group which as a function of alkaline processing effects a substantial change in the diffusivity of at least the Col portion of the compound.

After exposure, a photographic element as described above is treated with an alkaline processing solution to effect imagewise discrimination in the element. As mentioned previously, the imagewise discrimination is generally brought about by the monitoring or carrier group which, in the presence of the alkaline processing solution, is responsible for a substantial change in the diffusivity of at least the dye portion of the dye-providing material. As is known in the art, the dye-providing material can be initially immobile or initially mobile in the processing solution. Upon alkaline processing of an initially immobile dye-providing material, a mobile dye can be released imagewise or the material can be imagewise rendered soluble and thus mobile. If the material is initially mobile, the processing solution typically renders the material insoluble (and thus immobile) in an imagewise fashion.

It is well known in the art to utilize image dye-providing materials in a photographic element wherein an imagewise exposed element can be contacted with an alkaline processing solution to effect an imagewise difference in mobility of at least a portion of the dye-providing material, i.e., to effect release of a dye or dye precursor, to render said compound insoluble or soluble. It is the particular carrier or monitoring group which determines what form the change in diffusivity (of at least the dye portion of the material) will take. In certain instances, an increase in solubility of a given compound can be accomplished by substantially reducing the molecular weight of the compound; see, for example, the disclosure of Gompf U.S. Pat. No. 3,698,897, issued Oct. 17, 1972, in Fleckenstein et al allowed Ser. No. 351,763, a continuation-in-part of Ser. No. 282,796, filed Aug. 22, 1972, entitled PHOTOGRAPHIC SYSTEMS, in Anderson et al Ser. No. U.S. Pat. No. 3,725,062, filed July 6, 1971, entitled COLOR DIFFUSION TRANSFER PROCESSES and others. Exemplary of systems wherein the dye-providing compound splits off a dye are those described in Whitmore U.S. Pat. No. 3,227,552, issued Jan. 4, 1966, and Bloom U.S. Pat. No. 3,443,940, issued May 13, 1969, and Canadian Pat. No. 602,607, issued Aug. 2, 1960. Similarly, Yutzy U.S. Pat. No. 2,756,142, issued July 24, 1956, U.S. Pat. No. 2,774,668, issued Dec. 18, 1956, and U.S. Pat. No. 2,983,606, issued May 9, 1961, describe photographic elements wherein a dye-providing compound is rendered immobile in an imagewise fashion.

All of these prior systems have utility; however, it is desired to provide new compounds which provide new dyes having especially advantageous properties, such as improved hue, diffusibility, mordantability and the like.

We have found a class of cyan, azo dye-providing compounds well suited for use in color diffusion transfer color elements. The dye-providing compounds, as a function of typical processing under alkaline conditions, provide a cyan-colored substance having a mobility different than that of the compound.

The objects of the present invention are achieved through the use, in color diffusion transfer elements, of a new class of cyan, azo dye-providing compounds as well as the dyes provided thereby. Typically, these compounds are utilized in a photosensitive element which comprises a support having thereon at least one photosensitive silver halide emulsion, and at least one of said layers having associated therewith a cyan, azo dye-providing compound of this invention.

When Z represents lower alkyl-NH- (i.e., an alkyl group having 1 to about 4 carbon atoms), the dyes thus represented may be released by the reactions described in Hinshaw et al., U.S. Ser. No. 326,628. The especially preferred released dyes of our invention are those represented by Formulas IV and V above when Z represents --SO.sub.2 NH.sub.2. These dyes may be released by the reactions described in Fleckenstein et al allowed Ser. No. 351,763, a continuation-in-part of., U.S. Ser. No. 282,796 from the carrier moieties described by Formula III.

A suitable process for producing a photographic transfer image in color using the compounds of our invention, for example those wherein Car is as shown in Formula III, comprises the steps of:

1. treating the above-described photosensitive element with an alkaline processing composition in the presence of a silver halide developing agent to effect development of each of the exposed silver halide emulsion layers, thereby oxidizing the developing agent and the oxidized developing agent in turn cross-oxidizing the sulfonamido compound;

2. forming an imagewise distribution of diffusible released dye as a function of the imagewise exposure of each of the silver halide emulsion layers by cleaving each cross-oxidized sulfonamido compound; and

3. diffusing to a dye image-receiving layer at least a portion of each of the imagewise distributions of diffusible released dye to provide an image.

The photosensitive element in the above-described process can be treated with an alkaline processing composition to effect or initiate development in any manner. A preferred method for applying processing composition is by use of a rupturable container or pod which contains the composition. In general, the processing composition employed in our system contains the developing agent for development, although the composition could also just be an alkaline solution where the developer is incorporated in the photosensitive element, in which case the alkaline solution serves to activate the incorporated developer.

A photographic film unit according to our invention which is adapted to be processed by passing the unit between a pair of juxtaposed pressure-applying members, comprises:

1. a photosensitive element as described above; 2. a dye image-receiving layer; and 3. means for discharging an alkaline processing composition within the film unit such as a rupturable container which is adapted to be positioned during processing of the film unit so that a compressive force applied to the container by the pressure-applying members will effect a discharge of the contents of the container within the film unit; the film unit containing a silver halide developing agent.

The dye image-receiving layer in the above-described film unit can be located on a separate support adapted to be superposed on the photosensitive element after exposure thereof. Such image-receiving elements are generally disclosed, for example, in U.S. Pat. No. 3,362,819. When the means for discharging the processing composition is a rupturable container, typically it is positioned in relation to the photosensitive element and the image-receiving element so that a compressive force applied to the container by pressure-applying members, such as found in a camera designed for in-camera processing, will effect a discharge of the contents of the container between the image-receiving element and the outermost layer of the photosensitive element. After processing, the dye image-receiving element is separated from the photosensitive element.

The dye image-receiving layer in the above-described film unit can also be located integral with the photosensitive silver halide emulsion layer. One useful format for integral receiver-negative photosensitive elements is disclosed in Belgian Pat. No. 757,960. In such an embodiment, the support for the photosensitive element is transparent and is coated with an image-receiving layer, a substantially opaque light reflective layer, e.g., TiO.sub.2, and then the photosensitive layer of layers described above. After exposure of the photosensitive element, a rupturable container containing an alkaline processing composition and an opaque process sheet are brought into superposed position. Pressure-applying members in the camera rupture the container and spread processing composition over the photosensitive element as the film unit is withdrawn from the camera. The processing composition develops each exposed silver halide emulsion layer and dye images are formed as a function of development which diffuse to the image-receiving layer to provide a position, right-reading image which is viewed through the transparent support on the opaque reflecting layer background.

Another format for integral negative-receiver photosensitive elements in which the present invention can be employed is disclosed in Belgian Pat. No. 757,959. In this embodiment, the support for the photosensitive element is transparent and is coated with the image-receiving layer, a substantially opaque, light-reflective layer and the photosensitive layer or layers described above. A rupturable container containing an alkaline processing composition and an opacifier is positioned adjacent to the top layer and a transparent top sheet. The film unit is placed in a camera, exposed through the transparent top sheet and then passed through a pair of pressure-applying members in the camera as it is being removed therefrom. The pressure-applying members rupture the container and spread processing composition and opacifier over the negative portion of the film unit to render it light insensitive. The processing composition develops each silver halide layer and dye images are formed as a result of development which diffuse to the image-receiving layer to provide a right-reading image that is viewed through the transparent support on the opaque reflecting layer background.

Still other useful integral formats in which our sulfonamido compounds can be employed are described in U.S. Pat. Nos. 3,415,644; 3,415,645; 3,415,646; 3,647,437; and 3,635,707.

The film unit or assembly of the present invention can be used to produce positive images in single or multicolors. In a three-color system, each silver halide emulsion layer of the film assembly will have associated therewith an image dye-providing material possessing a predominant spectral absorption within the region of the visible spectrum to which said silver halide emulsion is sensitive, i.e., the blue-sensitive silver halide emulsion layer will have a yellow image dye-providing material associated therewith, the green-sensitive silver halide emulsion layer will have a magenta image dye-providing material associated therewith, and the red-sensitive silver halide emulsion layer will have a cyan image dye-providing material associated therewith. The image dye-providing material associated with each silver halide emulsion layer can be contained either in the silver halide emulsion layer itself or in a layer contiguous to the silver halide emulsion layer. The cyan image dye-providing material will, of course, be a compound of this invention.

When G is a hydrolyzable acyloxy group, the absorption spectrum of the azo dye is shifted to shorter wavelength. "Shifted dyes" of this type absorb light outside the range to which the associated silver halide layer is sensitive. The use of certain related shifted azo dye developers is described in U.S. Pat. No. 3,307,947 issued Mar. 7, 1967. The shifted dye-providing materials of this invention can be advantageously contained in the silver halide emulsion layer without substantially reducing the sensitivity of the layer. The acyloxy group is hydrolyzed by the alkaline processing composition, releasing the cyan dye of the desired hue. The yellow and magenta image dye-providing materials can be selected from a variety of materials such as those compounds described by Fleckenstein et al U.S. Ser. No. 282,796, mentioned previously. Additional useful magenta image dye-providing materials are described in co-filed Haase et al application Ser. No. 331,729, entitled "Novel Compounds and Photographic Materials."

The concentration of the compounds, which preferably are alkalicleavable upon oxidation, that are employed in the present invention can be varied over a wide range depending upon the particular compound employed and the results which are desired. For example, the image dye-providing compounds of the present invention can be coated in layers as dispersions in a hydrophilic film-forming natural or synthetic polymer, such as gelatin, polyvinyl alcohol, etc., which is adapted to be permeated by aqueous alkaline processing composition. Preferably, the ratio of dye-providing compound to polymer will be about 0.25 to about 4.0. The present compounds may then be incorporated in a gelatin by techniques known in the art (e.g., a high boiling, water immiscible organic solvent or a low boiling or water miscible organic solvent).

Depending upon which Car is used on the present compounds, a variety of silver halide developing agents can be employed in our invention. If the carrier used is that of Formula III, any silver halide developing agent can be used as long as it cross-oxidizes with the image dye-providing compounds used herein. The developer can be employed in the photosensitive element to be activated by the alkaline processing composition. Specific examples of developers which can be employed in our invention include hydroquinone, aminophenols, e.g., N-methylaminophenol, Phenidone (1-phenyl-3-pyrazolidone) trademark of Ilford, Ltd.; Dimezone (1-phenyl-4,4-dimethyl-3-pyrazolidone) trademark of Eastman Kodak Company; 1-phenyl-4-methyl-4-hydroxymethyl-3-pyrazolidone, N,N-diethyl-p-phenylenediamine, 3-methyl-N,N-diethyl-p-phenylenediamine, 3-methoxy-N,N-diethyl-p-phenylenediamine, etc. The black-and-white developers in this list are preferred, in that they have a reduced propensity of staining the dye image-receiving layer.

In a preferred embodiment of our invention, the silver halide developer in our process becomes oxidized upon development and reduces silver halide to silver metal. The oxidized developer then cross-oxidizes the sulfonamido-phenol or sulfonamido-naphthol dye-releasing compound. The product of cross-oxidation then undergoes alkaline hydrolysis, thus releasing an imagewise distribution of diffusible anionic dye which then diffuses to the receiving layer to provide the dye image. The diffusible moiety is transferable in alkaline processing composition either by virtue of its self-diffusivity or by having attached to it one or more solubilizing groups such as --COOH, -SO.sub.3 H, --SO.sub.2 NR.sup.5 R.sup.6, OH, etc. (where R.sup.5 and R.sup.6 are as described previously with at least one being hydrogen).

In using the especially preferred dye-releasing compounds according to our invention, the production of diffusible dye images is a function of development of the silver halide emulsions with a silver halide developing agent to form either negative or direct positive silver images in the emulsion layers. If the silver halide emulsion employed forms a direct positive silver image, such as a direct positive internal-image emulsion or a solarizing emulsion, which develops in unexposed areas, a positive image can be obtained on the dye image-receiving layer. After exposure of the film unit, the alkaline processing composition permeates the various layers to initiate development in the unexposed photosensitive silver halide emulsion layers. The developing agent present in the film unit develops each of the silver halide emulsion layers in the unexposed areas (since the silver halide emulsions are direct-positive ones), thus causing the developing agent to become oxidized imagewise corresponding to the unexposed areas of the direct-positive silver halide emulsion layers. The oxidized developing agent then cross-oxidizes the dye-releasing compounds and the oxidized form of the compounds then undergoes a base-catalyzed reaction in a preferred embodiment of our invention, to release the preformed dyes imagewise as a function of the imagewise exposure of each of the silver halide emulsion layers. At least a portion of the imagewise distributions of diffusible dyes diffuse to the image-receiving layer to form a positive image of the original subject. After being contacted by the lakaline processing composition, a pH-lowering layer in the film unit lowers the pH of the film unit (or the image-receiving unit) to stabilize the image.

Internal-image silver halide emulsions useful in those embodiments wherein a dye is released as a function of oxidation are direct-positive emulsions that form latent images predominantly inside the silver halide grains, as distinguished from silver halide grains that form latent images predominantly on the surface thereof. Such internal-image emulsions are described by Davey et al in U.S. Pat. No. 2,592,250, issued Apr. 8, 1952, and elsewhere in the literature. Other useful emulsions are described in U.S. Pat. No. 3,761,276, dated Sept. 25, 1973. Internal-image silver halide emulsions can be defined in terms of the increased maximum density obtained when developed with "internal-type" developers over that obtained when developed with "surface-type" developers. Suitable internal-image emulsions are those which, when measured according to normal photographic techniques by coating a test portion of the silver halide emulsion on a transparent support, exposing to a light-intensity scale having a fixed time between 0.01 and 1 second, and developing for 3 minutes at 20.degree.C. in Developer A below ("internal-type" developer), have a maximum density at least five times the maximum density obtained when an equally exposed silver halide emulsion is developed for 4 minutes at 20.degree.C. in Developer B described below ("surface-type" developer). Preferably, the maximum density in Developer A is at least 0.5 density unit greater than the maximum density in Developer B.

The internal-image silver halide emulsions when processed in the presence of fogging or nucleating agents provide direct positive silver images. Such emulsions are particularly useful in the above-described embodiment. Suitable fogging agents include the hydrazines disclosed in Ives U.S. Pat. Nos. 2,588,982 issued Mar. 11, 1952, and 2,563,785 issued Aug. 7, 1951; the hydrazides and hydrazones disclosed in Whitmore U.S. Pat. No. 3,227,552 issued Jan. 4, 1966; hydrazone quaternary salts described in Lincoln and Heseltine U.S. Pat. No. 3,615,615 issued Oct. 16, 1971; hydrazone containing polymethine dyes described in Spence and Janssen U.S. Pat. No. 3,718,470 issued Feb. 27, 1973; or mixtures thereof. The quantity of fogging agent employed can be widely varied depending upon the results desired. Generally, the concentration of fogging agent is from about 0.4 to about 8 grams per mole of silver in the photosensitive layer in the photosensitive element or from about 0.1 to about 2 grams per liter of developer if it is located in the developer. The fogging agents described in U.S. Pat. Nos. 3,615,615 and 3,718,470, however, are preferably used in concentrations of about 0.5 to 10.0 grams per mole of silver in the photosensitive layer.

The solarizing direct-positive silver halide emulsions useful in the above-described embodiment are well-known silver halide emulsions which have been effectively fogged either chemically, such as by the use of reducing agents, or by radiation to a point which corresponds approximately to the maximum density of the reversal curve as shown by Mees, The Theory of the Photographic Process, published by the Macmillan Co., New York, New York, 1942, pages 261-297. Typical methods for the preparation of solarizing emulsions are shown by Groves British Pat. No. 443,245, Feb. 25, 1936, who subjected emulsions to Roentgen rays "until an emulsion layer formed therefrom, when developed without preliminary exposure, is blackened up to the apex of its graduation curve"; Szaz British Pat. No. 462,730, Mar. 15, 1937, the use of either light or chemicals such as silver nitrate, to convert ordinary silver halide emulsions to solarizing direct positive emulsions; and Arens U.S. Pat. No. 2,005,837, June 25, 1935, the use of silver nitrate and other compounds in conjunction with heat to effect solarization. Particularly useful are the fogged direct-positive emulsions of Berriman U.S. Pat. No. 3,367,778; Illingsworth U.S. Pat. Nos. 3,501,305, 3,501,306 and 3,501,307; and combinations thereof.

Other embodiments in which our imaging chemistry can be employed include the techniques described in U.S. Pat. Nos. 3,227,550, 3,227,551, 3,227,552 and 3,364,022.

If photographic elements are used which contain compounds of this invention wherein Car is a silver halide developer as described, for example, in U.S. Pat. No. 2,983,606, when the liquid processing composition is applied, it permeates the emulsion to provide a solution of the dye developer substantially uniformly distributed in the emulsion. As the exposed silver halide emulsion is developed to a negative silver image, the oxidation product of the dye developer is immobilized or precipitated in situ with the developed silver, thereby providing an imagewise distribution of unoxidized dye developer dissolved in the liquid processing composition. This immobilization is apparently due, at least in part, to a change in the solubility characteristics of the dye developer upon oxidation. At least part of this imagewise distribution of unoxidized dye-developer is transferred to a superposed image-receiving layer to provide a transfer image.

Negative silver halide emulsions useful in certain embodiments of this invention, such as the above, can comprise, for example, silver chloride, silver bromide, silver chlorobromide, silver bromoiodide, silver chlorobromiodide or mixtures thereof. The emulsions can be coarse-or fine-grain and can be prepared by any of the well-known procedures, e.g., single-jet emulsions such as those described in TRivelli and Smith, The Photographic Journal, Vol. LXXIX, May, 1939 (pp. 330-338), double-jet emulsions, such as Lippmann emulsions, ammoniacal emulsions, thiocyanate or thioether ripened emulsions such as those described in Nietz et al U.S. Pat. No. 2,222,264 issued Nov. 19, 1940; Illingsworth U.S. Pat. No. 3,320,069 issued May 16, 1967; and Jones U.S. Pat. No. 3,574,628 issued Apr. 13, 1971. The emulsions may be monodispersed regular-grain emulsions such as the type described in Klein and Moisar, J. Phot. Sci., Vol. 12, No. 5, Sept./Oct., 1964 (pp. 242-251).

Another embodiment of our invention uses the image-reversing technique disclosed in British Pat. No. 904,364, page 19, lines 1-41. In this system our dye-providing compounds are used in combination with physical development nuclei in a nuclei layer contiguous to the photosensitive silver halide negative emulsion layer. The film unit contains a silver halide solvent, preferably in a rupturable container with the alkaline processing composition.

The various silver halide emulsion layers of a color film assembly of the invention can be disposed in the usual order, i.e., the blue-sensitive silver halide emulsion layer first with respect to the exposure side, followed by the green-sensitive and red-sensitive silver halide emulsion layers. If desired, a yellow dye layer or a yellow colloidal silver layer can be present between the blue-sensitive and green-sensitive silver halide emulsion layer for absorbing or filtering blue radiation that may be transmitted through the blue-sensitive layer. If desired, the selectivity sensitized silver halide emulsion layers can be disposed in a different order, e.g., the blue-sensitive layer first with respect to the exposure side, followed by the red-sensitive and green-sensitive layers.

The rupturable container employed in this invention can be of the type disclosed in U.S. Pat. Nos. 2,543,181; 2,643,886; 2,653,732; 2,724,051; 3,056,492; 3,056,491 and 3,152,515. In general, such containers comprise a rectangular sheet of fluid- and air-impervious material folded longitudinally upon itself to form two walls which are sealed to one another along their longitudinal and end margins to form a cavity in which processing solution is contained.

In a color film unit according to this invention, each silver halide emulsion layer containing a dye image-providing material or having the dye image-providing material present in a contiguous layer may be separated from the other silver halide emulsion layers in the image-forming portion of the film unit by materials including gelatin, calcium alginate, or any of those disclosed in U.S. Pat. No. 3,384,483, polymeric materials such as polyvinylamides as disclosed in U.S. Pat. No. 3,421,892, or any of those disclosed in French Pat. No. 2,028,236 or U.S. Pat. Nos. 2,992,104; 3,043,692; 3,044,873; 3,061,428; 3,069,263; 3,069,264; 3,121,011; and 3,427,158.

Generally speaking, except where noted otherwise, the silver halide emulsion layers in the invention comprise photosensitive silver halide dispersed in gelatin and are about 0.6 to 6 microns in thickness; the dye image-providing materials are dispersed in an aqueous alkaline solution-permeable polymeric binder, such as gelatin, as a separate layer about 1 to 7 microns in thickness; and the alkaline solution-permeable polymeric interlayers, e.g., gelatin, are about 1 to 5 microns in thickness. Of course, these thicknesses are approximate only and can be modified according to the product desired.

Any material can be employed as the image-receiving layer in this invention as long as the desired function of mordanting or otherwise fixing the dye images will be obtained. The particular material chosen will, of course, depend upon the dye to be mordanted. If acid dyes are to be mordanted, the image-receiving layer can contain basic polymeric mordants such as polymers of amino guanidine derivatives of vinyl methyl ketone such as described in Minsk U.S. Pat. No. 2,882,156, issued Apr. 14, 1959, and basic polymeric mordants such as described in Cohen et al U.S. Pat. No. 3,625,694, issued Dec. 7, 1971; U.S. Pat. No. 3,709,690, issued Jan. 9, 1973; and U.S. application Ser. No. 400,778, filed Sept. 26, 1973. See also U.S. application Ser. No. 412,992 of Burness et al, filed Nov. 5, 1973.

Preferred mordants are cationic mordants such as polymeric compounds composed of a polymer having quaternary nitrogen groups and at least two aromatic nuclei for each quaternary nitrogen in the polymer cation (i.e., having at least two aromatic nuclei for each positively charged nitrogen atom), such polymeric compounds being substantially free of carboxy groups. Useful mordants of this type are comprised of units of the following formula in copolymerized relationship with units of at least one other ethylenically unsaturated monomer: ##EQU17## wherein R.sup.7 and R.sup.8 each represent a hydrogen atom or a lower alkyl radical (of 1 to about 6 carbon atoms) and R.sup.8 can additionally be a group containing at least one aromatic nucleus (e.g., phenyl, naphthyl, tolyl); Q can be a divalent alkylene radical (of 1 to about 6 carbon atoms), a divalent arylene radical, a divalent aralkylene radical, a divalent arylenealkylene radical, such as ##SPC23## ##EQU18## wherein R.sup.12 is an alkylene radical, or R.sup.8 can be taken together with Q to form a ##EQU19## group; R.sup.9, R.sup.10 and R.sup.11 can be alkyl, aralkyl or aryl, or R.sup.9 and R.sup.10 and the nitrogen atom to which they are attached can together with Q represent the atoms and bonds necessary to form a quaternized nitrogen-containing heterocyclic ring, and X .sup.- is a monovalent negative salt-forming radical or atom in ionic relationship with the positive salt-forming radical, wherein said polymer is substantially free of carboxy groups and wherein the positive salt forming radical of said polymer comprises at least two aryl groups for each quaternary nitrogen atom in said polymer. In one preferred embodiment, Q represents a phenylene or substituted phenylene radical and R.sup.9, R.sup.10 and R.sup.11 are the same or different and represent alkyl groups, the sum of their carbon atoms exceeding 12. These preferred polymeric cationic mordants are described further in the above-mentioned U.S. Pat. No. 3,709,690 and U.S. application Ser. No. 400,778, incorporated herein by reference.

Other mordants useful in our invention include poly-4-vinylpyridine, the 2-vinyl pyridine polymer methyl-p-toluene sulfonate and similar compounds described in Sprague et al U.S. Pat. No. 2,484,430, issued Oct. 11, 1949, and cetyl trimethylammonium bromide, etc. Effective mordanting compositions are also described in Whitmore U.S. Pat. No. 3,271,148 and Bush U.S. Pat. No. 3,271,147, both issued Sept. 6, 1966.

Generally, good results are obtained when the image-receiving layer, preferably alkaline solution-permeable, is transparent and about 0.25 to about 0.40 mil in thickness. This thickness, of course, can be modified depending upon the result desired. The image-receiving layer can also contain ultraviolet absorbing materials to protect the mordanted dye images from fading due to ultraviolet light, brightening agents such as the stilbenes, coumarins, triazines, oxazoles, dye stabilizers such as the chromanols, alkylphenols, etc.

Use of a pH-lowering material in the dye image-receiving element of a film unit according to the invention will usually increase the stability of the transferred image. Generally, the pH-lowering material will effect a reduction in the pH of the image layer from about 13 or 14 to at least 11 and preferably 4-8 within a short time after imbibition. For example, polymeric acids as disclosed in U.S. Pat. No. 3,362,819, or solid acids or metallic salts, e.g., zinc acetate, zinc sulfate, magnesium acetate, etc., as disclosed in U.S. Pat. No. 2,584,030 may be employed with good results. Such pH-lowering materials reduce the pH of the film unit after development to terminate development and substantially reduce further dye transfer and thus stabilize the dye image.

An inert timing or spacer layer can be employed in the practice of our invention over the pH-lowering layer which "times" or controls the pH reduction as a function of the rate at which alkali diffuses through the inert spacer layer. Examples of such timing layers include gelatin, polyvinyl alcohol or any of those disclosed in U.S. Pat. No. 3,455,686. The timing layer may be effective in evening out the various reaction rates over a wide range of temperatures, e.g., premature pH reduction is prevented when imbibition is effected at temperatures above room temperature, for example, at 95.degree.-100.degree.F. The timing layer is usually about 0.1 to about 0.7 mil in thickness. Especially good results are obtained when the timing layer comprises a hydrolyzable polymer or a mixture of such polymers which are slowly hydrolyzed by the processing composition. Examples of such hydrolyzable polymers include polyvinyl acetate, polyamides, cellulose esters, etc.

The alkaline processing composition employed in this invention is the conventional aqueous solution of an alkaline material, e.g., sodium hydroxide, sodium carbonate or an amine such as diethylamine, preferably possessing a pH in excess of 11, and preferably containing a developing agent as described previously. The solution also preferably contains a viscosity-increasing compound such as a high-molecular-weight polymer, e.g., a water-soluble ether inert to alkaline solutions such as hydroxyethyl cellulose or alkali metal salts of carboxymethyl cellulose such as sodium carboxymethyl cellulose. A concentration of viscosity-increasing compound of about 1 to about 5 percent by weight of the processing composition is preferred which will impart thereto a viscosity of about 100 cp. to about 200,000 cp. In certain embodiments of our invention, an opacifying agent, e.g., TiO.sub.2, carbon black, pH indicator dyes, etc., may be added to the processing composition.

While the alkaline processing composition used in this invention can be employed in a rupturable container, as described previously, to conveniently facilitate the introduction of processing composition into the film unit, other methods of inserting processing composition into the film unit could also be employed, e.g., interjecting processing solution with communicating members similar to hypodermic syringes which are attached either to a camera or camera cartridge.

The alkaline solution-permeable, substantially opaque, light-reflective layer employed in certain embodiments of photographic film units of our invention can generally comprise any opacifier dispersed in a binder as long as it has the desired properties. Particularly desirable are white light-reflective layers since they would be esthetically pleasing backgrounds on which to view a transferred dye image and would also possess the optical properties desired for reflection of incident radiation. Suitable opacifying agents include titanium dioxide, barium sulfate, zinc oxide, barium stearate, silver flake, silicates, alumina, zirconium oxide, zirconium acetyl acetate, sodium zirconium sulfate, kaolin, mica, or mixtures thereof in widely varying amounts depending upon the degree of opacity desired. The opacifying agents may be dispersed in any binder such as an alkaline solution-permeable polymeric matrix such as, for example, gelatin, polyvinyl alcohol, and the like. Brightening agents such as the stilbenes, coumarins, triazines and oxazoles can also be added to the light-reflective layer, if desired. When it is desired to increase the opacifying capacity of the light-reflective layer, dark-colored opacifying agents, e.g., carbon black, nigrosine dyes, etc., may be added to it, or coated in a separate layer adjacent to the light-reflective layer.

The supports for the photographic elements of this invention can be any material as long as it does not deleteriously effect the photographic properties of the film unit and is dimensionally stable. Typical flexible sheet materials include cellulose nitrate film, cellulose acetate film, poly(vinyl acetal) film, polystyrene film, poly(ethyleneterephthalate) film, polycarbonate film, poly-.alpha.-olefins such as polyethylene and polypropylene film, and related films or resinous materials. The support can be from about 2 to about 9 mils in thickness.

The silver halide emulsions useful in our invention are well known to those skilled in the art and are described in Product Licensing Index, Vol. 92, December, 1971, publication 9232, p. 107, paragraph I, "Emulsion types"; they may be chemically and spectrally sensitized as described on page 107, paragraph III, "Chemical sensitization," and pp. 108-109, paragraph XV, "Spectral sensitization," of the above article; they can be protected against the production of fog and can be stabilized against loss of sensitivity during keeping by employing the materials described on p. 107, paragraph V, "Antifoggants and stabilizers," of the above article; they can contain development modifiers, hardeners, and coating aids as described on pp. 107-108, paragraph IV, "Development modifiers"; paragraph VII, "Hardeners"; and paragraph XII, "Coating aids", of the above article; they and other layers in the photographic elements used in this invention can contain plasticizers, vehicles and filter dyes described on p. 108, paragraph XI, "Plasticizers and lubricants," and paragraph VIII, "Vehicles," and p. 109, paragraph XVI, "Absorbing and filter dyes," of the above article; they and other layers in the photographic elements used in this invention may contain addenda which are incorporated by using the procedures described on p. 109, paragraph XVII, "Methods of addition," of the above article; and they can be coated by using the various techniques described on p. 109, paragraph XVIII, "Coating procedures," of the above article, the disclosures of which are hereby incorporated by reference.

It will be appreciated that there remains in the photographic element after transfer has taken place an imagewise distribution of dye in addition to developed silver. A color image comprising residual nondiffusible compound may be obtained in this element if the residual silver and silver halide are removed by any conventional manner well known to those skilled in the photographic art, such as a bleach bath followed by a fix bath, a bleach-fix bath, etc. The imagewise distribution of dye may also diffuse out of the element into these baths, if desired, rather than to an image-receiving element. If a negative-working silver halide emulsion is employed in such photosensitive element, then a positive color image, such as a color transparency or motion-picture film, may be produced in this manner. If a direct-positive silver halide emulsion is employed in such photosensitive element, then a negative color image may be produced.

Preferably, when the desired dye image is retained in the image-forming unit, the image dye-providing materials are shifted (G is hydrolyzable acyloxy) and are incorporated in the silver halide emulsion layer. Improved processes are described in U.S. Ser. No. 422,390, filed Dec. 6, 1973.

The following examples are provided for a further understanding of the invention. The structures of all of the compounds were confirmed by their infrared and NMR spectra and in some cases by elemental analysis. The notation C.sub.5 H.sub.11 -t as used herein as an abbreviation for t-pentyl.

EXAMPLE 12 - Photographic Testing

The above image dye-providing compounds were tested for reactivity and diffusibility of their released dyes to a receiving element. Each compound was dissolved in an equal weight of diethyllauramide and finely dispersed in gelatin. The dispersion was added to a 0.8 .mu.m monodispersed negative-working gelatino-silver bromide emulsion which was coated on a polyester film support, the coverage of compound being about 1.1 .times. 10.sup.-.sup.5 moles/dm.sup.2 ; silver - 9.2 mg/dm.sup.2 ; and gelatin - 32 mg/dm.sup.2. An overcoat layer of 8.6 g/dm.sup.2 of gelatin, hardened by formaldehyde was then applied.

A. Image discrimination - A sample of the above coating was exposed through a step-wedge and then laminated to a mordant-containing receiving element with a viscous processing composition (goo) by passing the "sandwich" between a pair of juxtaposed pressure-applying rollers. The receiving element consisted of a paper support on which was coated a mixture of gelatin (21 mg/dm.sup.2) and a mordant, poly[styrene-co-N-benzyl-N,N-dimethyl-N-(3-maleimidopropyl)ammonium chloride] (21 mg/dm.sup.2). The goo contained, per liter of solution, 20 g. sodium hydroxide, 0.75 g. 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone, 10 g. potassium bromide and 25 g. hydroxyethylcellulose. After 60 seconds, the receiver was peeled apart and washed in water to adjust the pH to about 7. Good image density in the exposed areas was obtained with practically no transfer of dye in the unexposed areas. The Dmax and Dmin for each transfer is given under image discrimination in the table.

B. Spectrophotometry - The spectra of the released dyes when adsorbed to the mordant on a transparent support were measured spectrophotometrically. The maximum wavelength (.lambda.max) and the bandwidth in nm at one-half the density at the .lambda.max of the curve for each dye is also given in the table. This "half bandwidth" along with the .lambda.max is indicative of hue, the brightness and purity of color being greater, the smaller the half bandwidth.

C. Dye-transfer in receiving element - Another sample of an emulsion coating containing the image dye-providing compound was fogged by exposure to light and processed by passing it has a "sandwich" with an image receiving elment and viscous developing composition (goo) between a pair of juxtaposed pressure-applying rollers. The developer layer thickness of the resulting laminate ranged from about 0.075 to 0.10 mm. The receiving element had the following structure (the coverages in mg/dm.sup.2 are shown in parenthesis):Carbon (27) + Gelatin (17)TiO.sub.2 (215) + Gelatin (21)Mordant* (21) + Gelatin (11)Cellulose acetate support *Same as above.

The "goo" contained 20 g. sodium hydroxide, 0.75 g. 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidone, 10 g. potassium bromide and 25 g. hydroxyethylcellulose, all per liter of solution. Upon application of the goo to the fogged emulsion layer, the dyes are released and diffuse through the carbon and titania layers to the mordant layer. The density of the dyes on the mordant layer was read through the support by means of a reflection densitometer after intervals of 30, 60 and 120 seconds at 24.degree.C. The increase in density, as indicated by the values in the table, is a measure of the rate of release and also of the diffusivity of the dyes.

EXAMPLE 13 - Preparation of Compounds 12 and 12a

A mixture of 3 g. NaHCO.sub.3, 4.93 g. (8.10 mmol) Compound A, and 3.97 g. (8.10 mmol) of 1-hydroxy-4-amino-N-[4-(2,4-di-t-pentylphenoxy)-butyl]-2-naphthamide (referred to below as NH.sub.2 - Group) in 30 g. dry dimethylsulfoxide was stirred at 80.degree.-100.degree.C. for 60 minutes, cooled and poured onto ice water containing sufficient dilute HCl to neutralize the excess NaHCO.sub.3. The precipitated Compound 12 was filtered, washed with water, and air dried (crude dye cake yield = 102 percent). Compound 12 was quite clean as isolated but was chromatographed on a silica gelcellulose (equal parts by weight) dry packed column by ascending development with a solution of ethyl acetate (9 parts by volume) and methanol (1 part by volume). A schematic representation of the reactions involved is shown below: ##SPC36##

The compound was tested as in Example 12 and the released dye had a .lambda.max of 640 nm and Dmax of 2.35 at 60 seconds and 2.5 at 120 seconds. A similar compound (Compound 12a) having a cyano radical in place of the methylsulfonyl on the nitrophenyl ring also gave good results.

EXAMPLE 14 - Preparation of Compounds 13, 13a, 13b and 13c

A solution of 4.14 (5.00 mmol) of Coupler A in 20 ml. pyridine and 150 ml. 1:5 acid [propionic acid (1 volume):acetic acid (5 volumes)] was prepared and cooled to 5.degree.C. Meanwhile, a solution of 1.2 g. 2-amino-5-nitrobenzenesulfonic acid sodium salt (5.00 mmol) and 0.036 g. sodium nitrite (5.00 mmol) in 50 ml. water was cooled to 0.degree.C. and added dropwise to a solution of 1 ml. 37 percent HCl in 20 ml. of water at 0.degree.C. The diazotization was very rapid--the resulting suspension of diazonium salt was slowly added at 5.degree.C. to the coupler solution. The coupling was rapid (probably complete after 30 minutes at 5.degree.C.); however, the mixture was stirred at 5.degree.C. for 2 hours and the dye precipitated by the addition of ice water. The orange-red powder Compound 13 which was filtered, washed with cold water (5 liters) and vacuum dried was purified by chromatography on a silica gel-cellulose (equal parts by weight) dry packed column by ascending development with a solution of chloroform (8 parts by volume) and methanol (2 parts by volume). A schematic representation of the reactions involved is shown below. ##SPC37##

Compound 13 was tested as in Example 12 and found to have a transferred .lambda.max = 660 nm, densities: 0.33 (30 sec.), 0.66 (60 sec.) and 1.08 (120 sec.).

A similar compound (Compound 13a) having a sulfamoyl (--SO.sub.2 NH.sub.2) radical in place of the sulfo (--SO.sub.3 H) radical on the nitrophenyl ring was prepared and tested as in Example 12. This compound was found to have a transferred .lambda.max = 640 nm, D max = 0.82, densities: .53 (30 seconds), 0.71 (60 seconds), and 0.82 (120 seconds).

The above compound in diethyllauramide solvent was coated as a dispersion in gelatin on polyester support. The layer contained 7.1, 14, and 21 mg/dm.sup.2 of compound, solvent, and gelatin, respectively. A second layer contained a gelatino-silver bromoiodide emulsion with 11 mg/dm.sup.2 of silver and 22 mg/dm.sup.2 of gelatin. The coating was exposed, dipped in the processing composition below for 30 seconds and laminated for varying times with a receiving element containing a mordant layer of poly-4-vinylpyridine and polyvinyl alcohol on a paper support. The processing solution contained (G./liter of solution in water) potassium hydroxide (50), potassium bromide (40), N-benzyl-.alpha.-picolinium bromide (20), benzotriazole (20) and sodium sulfate (50). Upon delamination of separate samples after 30, 60, and 120 seconds, respectively, reflection densities of 1.20, 1.55, and 1.80 were measured on the receiver.

The reaction is protected from atmospheric moisture and stirred at room temperature for 4 hours. The reaction is cooled in an ice bath and a solution of 25 g. (0.3 mole) of sodium bicarbonate in 500 ml. of water is added in portions to precipitate an oily solid. An additional 500 ml. of water is added to complete the precipitation. The liquid is decanted from the oily solid and the solid is washed repeatedly with water until the water phase is almost colorless. Any oily solid removed in the original or subsequent decantations is recovered by filtration and thorough washing with water. The oily product is mechanically stirred in 250 ml. of water for 11/2 hours to give a crystalline material which is further ground up under water using a mortar and pestle. The resulting slurry is filtered, the solid is washed with water and dried to yield 52 g. (97 percent) of product, m.p. 120.degree.-160.degree.C. The crude product is purified by stirring the product in 300 ml. of acetic acid at room temperature for 11/2 hours. The solid is dissolved and reprecipitated. The slurry is filtered and the solid washed with 200 ml. of cold acetic acid followed by 500 ml. of water. The yield of the pure magenta image dye-providing compound is 38 g. (71 percent), m.p. 168.degree.-171.degree.C., .nu.max (Dimethylacetamide with triethylamine present) 520-545 nm.

The yellow image dye-providing compound used in this example is prepared as follows:

(0.015 mole) of 1-hydroxy-4-amino-N-[.DELTA.-(2,4-di-t-amylphenoxy)butyl]-2-naphthamide in 60 ml. of dye pyridine cooled to 2.degree.C. in an ice bath and stirred in a nitrogen atmosphere are added 6.4 g. (0.016 mole) of 1-phenyl-3-methylcarbamyl-4-(p-chlorosulfonylphenylazo)-5-pyrazolone. The mixture is stirred for 2 hours at room temperature and poured into 1 liter of ice and water containing 75 ml. of hydrochloric acid. The precipitate is collected, dried and recrystallized to give 10.4 g. of the yellow image dye-providing compound.

The photographic elements of this invention can be processed to provide a good positive image in the exposed element by a reversal process. The following example employs an image dye-providing compound adapted for use in the reactions claimed in Hinshaw et al, U.S. Ser. No. 326,628.
