Description

FIELD OF THE INVENTION

The present invention relates to a stabilizer for silver halide color photographic light-sensitive materials, a concentrated composition of said stabilizer and a processing method using said stabilizer. More specifically, the present invention relates to a processing technique excellent in stability of dye images, excellent in preservability of the concentrated composition, less in stains on the backside of a light-sensitive material, excellent in preservability of a stabilizer and less in flaws on a light-sensitive material subjected to high-speed transferring.

BACKGROUND OF THE INVENTION

In processing color photographic light-sensitive materials for photographing represented by photographic light-sensitive materials containing silver iodobromide as the silver halide, a stabilizer containing formaldehyde is used, in general, in the final processing bath which follows the washing bath.

Formaldehyde used in the stabilizing bath contributes to the improvement in properties of color photographic light-sensitive materials, particularly to the prevention of flaws on the surface of light-sensitive materials and the prevention of gradation changes which are associated with hardening of light-sensitive materials owing to aging. It is also known that formaldehyde has an effect of preventing deterioration in stability of dye images caused by a coupler left unreacted in color light-sensitive materials.

However, formaldehyde added in the stabilizer for the purpose of a stabilized dye image, etc., has a fault of adhering to light-sensitive materials and reacting with sulfite ions brought from the preceding bath to form adducts; this not only impairs the primary object of stabilizing dye images but also accelerates precipitation of sulfur or sulfides.

As a preventive measure against such a problem, U.S. Pat. No. 4,786,583 discloses use of alkanol amines, but alkanol amines are liable to cause yellow stains in unexposed portions and not necessarily satisfactory in preventing sulfur or sulfides from precipitating.

On the other hand, undesirable influences of formaldehyde upon the human body have been disclosed. In the United States, Chemical Industry Institute of Toxicology (CIIT) announced that rats developed naris cancers at a formaldehyde concentration of 15 ppm; National Institute for Occupational Safety and Health (NIOSH) and American Conference of Governmental Industrial Hygientists (ACCIH) also disclosed that formaldehyde might be carcinogenic. Use of formaldehyde is strictly regulated in Europe, too. In Germany, the formaldehyde concentration in residences has been regulated to be not more than 0.1 ppm since 10 years ago.

In Japan, use of formaldehyde is regulated for its toxicity of irritating the mucous membrane by the law for deleterious substances and powerful drugs, regulation to organic solvent toxication, according to the Occupational Safety and Health Law, the regulation on household goods, the regulation on textile goods and plywoods, and the regulation on underwear and baby clothes newly enforced in 1975 by the Ministry of Health and Welfare. Under such circumstances, there has been demanded a technique which enables reduction in amounts of formaldehyde to be used.

As means to make the formaldehyde content in stabilizers substantially zero or to reduce it effectively, there are proposed use of hexahydrotriazine compounds in Japanese Pat. O.P.I. Pub. Nos. 27742/1987 and 151538/1986 and use of N-methylol compounds in U.S. Pat. No. 4,859,574.

Though these hexahydrotriazine compounds can prevent dye images from fading under high temperature and high humidity conditions even when the formaldehyde concentration is substantially zero, these are less effective under low humidity conditions, for example, at a relative humidity not higher than 20%. Moreover, these compounds have a tendency to stain the backside of color light-sensitive materials for photographing due to uneven sagging of a stabilizer used and, further, have a disadvantage of lowering preservability of a stabilizer and are liable to-cause precipitation of sulfur or sulfides, though not so heavy as formaldehyde does; therefore, troubles are apt to arise in the cases of a protracted processing, a small processing amount and a small replenishing amount.

When the above N-methylol compounds are used in place of formaldehyde, these are insufficient not only in preventing fading of dye images and backside stains but also in improving preservability of a stabilizer; moreover, the preservability is noticeably deteriorated if a preventive measure is taken against the fading of dye images.

In a continuous method for processing a large amount of light-sensitive materials in an automatic processor, it is necessary to take a measure for keeping each component of a stabilizer at a constant concentration, in order to avoid deterioration in properties of the stabilizer due to change in concentration of the component. In addition, minimization of the replenishing amount is strongly demanded in recent years from the viewpoints of economy and antipollution.

A stabilizer may be prepared by mixing necessary components when it is used. But in general, to increase efficiency of the preparation, prescribed amounts of processing agents are mixed and dissolved in the form of concentrated solutions beforehand and, at the time of use, these concentrated solutions are mixed with one another and/or diluted with water to a uniform processing solution, which is used as a tank solution or a replenisher.

However, it is found that concentrated compositions containing formaldehyde and N-methylol compounds have a problem in preservability. Further, it is found that, in a high-speed conveyance during the rapid processing with a large-sized automatic processor practiced in recent years, light-sensitive materials become susceptible to flaws because pressure is applied to the lower turn roller in the stabilizing tank of an automatic processor.

PROBLEMS THE INVENTION INTENDS TO SOLVE

Accordingly, the object of the present invention is to provide a stabilizer for a silver halide color photographic light-sensitive material, a concentrated composition of said stabilizer and a method for processing the light-sensitive material, which are improved firstly in capability of preventing color fading under low humidity conditions in the substantial absence of formaldehyde, secondly in preservability of the concentrated composition, thirdly in capability of minimizing stains on the backside of the light-sensitive material, fourthly in capability of minimizing flaws on the light-sensitive material in a high-speed conveyance, and fifthly in safety of working environments.

When the compounds exemplified on pages 37-39 of Japanese Pat. Appl. No. 89686/1991 (these are Compounds SU-I-1 through SU-I-23 reproduced above), water soluble organic siloxane compounds having a polyoxyalkylene group, are added in an amount of 0.01 to 20 g per liter of stabilizer, favorable results are obtained, particularly formation of precipitates and yellow stains can be effectively prevented.

An addition amount not more than 0.01 g/l causes stains on a light-sensitive material; an addition amount not less than 20 g/l allows the organic siloxane compound to deposit on a light-sensitive material in large amounts and thereby accelerates formation of stains.

The water soluble organic siloxane compound of the invention means such generally known water soluble organic siloxane compounds as are described, for example, in 18333/1972, 62128/1974, Japanese Pat. Exam. Pub. Nos. 51172/1980, 37538/1976 and U.S. Pat. No. 3,545,970.

The following are examples from JP51172/1980 and JP 37538/1976: ##STR33##

These water soluble organic siloxane compounds are commercially available from Union Carbide Corp., Shin-Etsu Chemical Co., etc.

In the invention, the wording "substantially no formaldehyde is contained in a stabilizer" means that the amount of formaldehyde present is within a range from 0 to 0.2 g per liter of stabilizer.

In the invention, the amount of the stabilizer replenished is desirably not more than 800 ml per square meter of light-sensitive material. But, too small a replenishing amount causes fading of dyes and deposition of salts on a dried light-sensitive material; therefore, the amount is more desirably in a range from 100 to 620 ml/l . Further, the replenishing amount varies with the configuration of a stabilizing bath and can be decreased as the number of tanks increases.

The pH of the stabilizer of the invention is desirably within a range from 2 to 12, more desirably from 4 to 11 and most desirably from 5 to 10 for bringing out the effect of the invention satisfactorily. The temperature of the stabilizer is preferably 15.degree. to 70.degree. C., especially 20.degree. to 55.degree. C. Further, the processing time with the stabilizer is desirably not more than 120 seconds, more desirably 3 to 90 seconds and most desirably 6 to 60 seconds.

When two or more stabilizer tanks are employed in practicing the invention, it is preferable that these tanks be arranged in a countercurrent mode (a replenisher is fed to the rear bath and an overflow is poured into the preceding bath) in order to bring out the effect of the invention, particularly to minimize the pollution load and improve image preservability.

In the invention, it is preferable that the stabilizer contain a chelating agent having a chelate stability constant not less than 8 against iron ions. "Chelate stability constant" used here means a constant generally known by L. G. Sillen and A. E. Martell, "Stability Constant of Metal-ion Complexes", The Chemical Society, London (1964) and S. Chaberek and A. E. Martell, "Organic Sequestering Agents", John Wiley & Sons (1959), etc.

Typical examples of chelating agents having a chelate stability constant not less than 8 against ferric ions include those described in Japanese Pat. Appl. Nos. 234776/1990 and 324507/1989.

These chelating agents are used in an amount of preferably 0.01 to 50 g per liter of stabilizer; especially, an addition amount of 0.05 to 20 g per liter produces much better results.

An ammonium compound is preferably added to the stabilizer in the form of ammonium salts of inorganic compounds; the addition amount thereof is preferably 0.001 to 1.0 mole, especially 0.002 to 2.0 moles per liter of stabilizer.

Further, it is preferable that a metal salt be jointly used with the above chelating agent in the stabilizer. Examples of such a metal salt include salts of Ba, Ca, Ce, Co, In, La, Mn, Ni, Bi, Pb, Sn, Zn, Ti, Zr, Mg, A1 and Sr. And these are supplied in the form of inorganic salts or water soluble chelating agents such as halides, hydroxides, sulfates, carbonates, phosphates and acetates. The addition amount thereof is preferably 1.times.10.sup.-4 to 1.times.10.sup.-1 mole, especially 4.times.10.sup.-4 to 2.times.10.sup.-1 mole per liter of stabilizer.

Moreover, there may be added to the stabilizer an organic acid such as citric acid, acetic acid, succinic acid, oxalic acid or benzoic acid and a pH adjuster such as phosphates, borates, hydrochlorides or sulfates. These compounds are employed in an amount necessary to maintain the pH of the stabilizer and may be arbitrarily combined with one another within the limits not to exert harmful influences upon aging stability of photographic color images and formation of precipitates.

Syntheses of these exemplified compounds and application of them to other fields are described in U.S. Pat. Nos . 2,767,172, 2,767,173, 2,767,174, 2,870,015, British Pat. No. 848,130 and French Pat. No. 1,555,416. Some of them are commercially available under the trade names of Topcide 300, Topcide 600 (PERMACHEM. Asia Co.), Finecide J-700 (Tokyo Fine Chemicals Co.) and Proxel GXL (I.C.I. Ltd.).

These compounds of Formula (B-2) or (B-3) are used in an amount of preferably 0.001 to 20 g, especially 0.005 to 5 g per liter of stabilizer of the invention.

In the processing according to the invention, silver may be recovered. For example, there may be effectively employed the electrolysis method (disclosed in French Pat. No. 2,299,667), the precipitation method disclosed in Japanese Pat. O.P.I. Pub. No. 73037/1977, German Pat. No. 2,331,220), the ion exchange method (disclosed in Japanese Pat. O.P.I. Pub. No. 17114/1976, German Pat. No. 2,548,237) and the metal replacement method (disclosed in British Pat. No. 1,353,805). To improve the rapid processability, an in-line silver recovery from a tank solution by means of electrolysis or an anion exchange resin is particularly preferred, but the recovery may also be carried out from a waste overflow.

In addition, the stabilizer may be subjected to ion exchange, electrodialysis (see Japanese Pat. O.P.I. Pub. No. 28949/1986) or reverse osmosis (see Japanese Pat. O.P.I. Pub. Nos. 240153/1985, 254151/1987). It is also preferable that the water used in the stabilizer be deionized in advance. These means help to increase the antimold capability, stability of the stabilizer and the aging stability of dye images. Such a deionization treatment can be carried out by any means as long as it can reduce Ca and Mg ion content of a treated water to 5 ppm or less, but preferably, a treatment with an ion exchange resin or that with a reverse osmosis membrane is carried out singly or in combination. The deionization with an ion exchange resin and that with a reverse osmosis membrane are described in detail in KOKAI GIHO (Voluntary Technical Publication) Nos. 87-1987 and 89-20511.

After the stabilizing process, no washing process is required at all, but a short-time rinsing or a surface washing with a small amount of water may be carried out according to a specific requirement.

Color developing agents usable in the color developing process include aminophenol compounds and p-phenylenediamine compounds, and p-phenylenediamine compounds having a water-solubilizing group are preferred in the invention. Such water-solubilizing groups serve enough so long as at least one of them is present on the amino group or the benzene nucleus of the p-phenylenediamine compound.

Typical examples of the water-solubilizing group include --(CH.sub.2).sub.n --CH.sub.2 OH, --(CH.sub.2).sub.m --NHSO.sub.2 --(CH.sub.2).sub.n --CH.sub.3, --(CH.sub.2).sub.m O--(CH.sub.2).sub.n --CH.sub.3, --(CH.sub.2 CH.sub.2 O).sub.n C.sub.m H.sub.2m+1 (m and n each indicate an integer of 0 or more), --COOH and --SO.sub.3 H.

In the formula, A.sub.1 to A.sub.4 may be the same or different and each represent --CH.sub.2 OH, --COOM or --PO.sub.3 M.sub.1 M.sub.2, where M, M.sub.1 and M.sub.2 each represent a hydrogen atom, an alkali metal atom (e.g., sodium, potassium) or an ammonium group; X represents a substituted or unsubstituted alkylene group having 3 to 6 carbon atoms (e.g., propylene, butylene, pentamethylene); and the substituent is a hydroxyl group or an alkyl group having 1 to 3 carbon atoms. ##STR38##

In the formula, A.sub.1 to A.sub.4 are the same as the above; n represents an integer of 1 to 8; B.sub.1 and B.sub.2 may be the same or different and each represent a substituted or unsubstituted alkylene group having 2 to 5 carbon atoms (e.g., ethylene, propylene, butylene, pentamethylene); and the substituent is a hydroxyl group or a lower alkyl group having 1 to 3 carbon atoms (e.g., methyl, ethyl, propyl).

The following are typical examples of the compound represented by Formula (A) or (B) : ##STR39##

As ferric complex salts of these compounds (A-1) to (A-12) and (B-1) to (B-7), there may be arbitrarily used sodium salts, potassium salts or ammonium salts of ferric complexes of them.

Besides the above ferric complex salts of the compounds represented by Formula (A) or (B) , there may also be used as bleaching agents the compounds exemplified on pages 79-80 of Japanese Pat. Appl. No. 302784/1990.

When two or more of these organic acid ferric complex salts are used in combination, the ferric complex salts of the compounds represented by Formula (A) or (B) amounts to desirably 70% (in molar equivalent) or above, more desirably 80% or above, most desirably 90% or above and especially 95% or above in order to bring out the effect of the invention much more.

The rapid processability of the bleacher, bleach-fixer and stabilizer can be enhanced by adding thereto at least one compound selected from imidazole and its derivatives described in Japanese Pat. O.P.I. Pub. No. 295258/1989, the compounds represented by one of Formulas (I) to (IX) defined in the same Japanese patent publication and the exemplified compounds thereof.

No. 123459/1987, the compounds exemplified on pages 22-25 of Japanese Pat. O.P.I. Pub. No. 17445/1988 and the compounds described in Japanese Pat. O.P.I. Pub. Nos. 95630/1988, 28426/1988.

These accelerators may be used singly or in combination, the addition amount is desirably 0.01 to 100 g, more desirably 0.05 to 50 g, and most desirably 0.05 to 15 g per liter of bleacher.

The pH of the bleacher is preferably not more than 6.0, especially 1.0 to 5.5. The pH of the bleach-fixer is preferably 5.0 to 9.0, especially 6.0 to 8.5. The pH of the bleacher and that of the bleach-fixer defined here are pHs of respective processing baths in processing silver halide light-sensitive materials and clearly distinguished from the pH of a replenisher.

The bleacher or the bleach-fixer may contain other known photographic compounds.

The replenishing amount of the bleacher or the bleach-fixer is desirably not more than 500 ml, more desirably 20 to 400 ml, and most desirably 40 to 350 ml per square meter of silver halide light-sensitive material. The effect of the invention can be achieved more obviously as the replenishing amount decreases.

In the invention, air or oxygen may be blown into a processing bath and a replenisher storage tank if desired, or a suitable oxidizing agent such as hydrogen peroxide, a bromate or a persulfate may be added, in order to raise the activity of the bleacher or the bleach-fixer.

As fixing agents, conventional ones can be used in the fixer or the bleach-fixer, but preferred fixing agents are thiocyanates and thiosulfates.

The content of thiocyanates is preferably not less than 0.1 mol/l. When these are used in processing color negative films, the content is preferably not less than 0.3 mol/l, especially not less than 0.5 mol/l. Thiosulfates are used in an amount of preferably not less than 0.2 mol/l. In the case of processing color negative films, the content is preferably not less than 0.5 mol/l. Besides these fixing agents, conventional pH buffers may be employed singly or in combination in the fixer or the bleach-fixer.

In addition, it is preferable that an alkali halide or an ammonium halide, such as potassium bromide, sodium bromide, sodium chloride or ammonium bromide, be contained in a large amount as a rehalogenating agent. Further, there may also be added those compounds which are known as additives for a fixer or a bleach-fixer, such as alkylamines and polyethylene oxides.

Further, silver may be recovered from the fixer or the bleach-fixer according to a conventional method.

The replenishing amount of the fixer is usually 50 to 900 ml, preferably 100 to 500 ml per square meter of light-sensitive material.

The pH of the fixer is preferably 4 to 8.

It is preferable that a processing solution having a fixing capability contain the compound represented by the following Formula (FA) defined on page 56 of Japanese Pat. O.P.I. Pub. No. 295258/1989 or an exemplified compound thereof. This helps to bring out the effect of the invention much satisfactorily and to minimize formation of sludges in a processing solution having a fixing capability when small amounts of light-sensitive materials are processed over a long time. ##STR40##

The compounds expressed by Formula (FA) defined in the above patent publication can be synthesized by general methods described, for example, in U.S. Pat. Nos. 3,335,161 and 3,260,718. These compounds may be used singly or in combination of two or more.

The compounds of Formula (FA) produce good results when used in an amount of 0.1 to 200 g per liter of processing solution.

In the invention, the processing time with the bleacher and that with the fixer may be arbitrarily selected, but these are desirably not longer than 3 min and 30 sec, more desirably 10 sec to 2 min and 20 sec and most desirably 20 sec to 1 min and 20 sec, respectively. The processing time with the bleach-fixer is desirably not longer than 4 min, more desirably 10 sec to 2 min and 20 Sec.

In the processing method according to the invention, it is preferable that the bleacher, the bleach-fixer or the fixer be subjected to forced stirring for the purpose of bringing out the effect of the invention noticeably and enhancing the rapid processability. "Forced stirring"0 means that the stirring is forcedly carried out by use of a stirring means, unlike the move of a solution due to diffusion. As means for such forced stirring, there can be used stirring means disclosed in Japanese Pat. O.P.I. Pub. Nos. 222259/1989 and 206343/1989.

In the invention, when the crossover time from a color developing bath to a bleaching bath or a bleach-fixing bath is kept within 10 seconds, preferably within 7 seconds, bleach fogs can be prevented as another effect of the invention.

Besides the above compounds contained in processing solutions used in the processing method of the invention, these processing solutions may contain the following additives.

The bleacher may contain conventional additives such as bleaching agents, pH regulators, acids and the addition amount of the acids and bleach accelerators described on pages 3-4 of Japanese Pat. O.P.I. Pub. No. 44347/1990 and on pages 37-38 of Japanese Pat. O.P.I. Pub. No. 43546/1990. The fixer may use conventional additives such as fixing agents, fixing accelerators, preservatives and chelating agents described on page 4 of Japanese Pat. O.P.I. Pub. No. 44347/1990. The bleach-fixing may use those described on pages 37-38 of Japanese Pat. O.P.I. Pub. No. 43546/1990. The stabilizer of the invention may employ bactricides, antimolds, chalating agents and optical whitening agents described on pages 38-39 of Japanese Pat. O.P.I. Pub. No. 43546/1990.

Stabilizer and stabilizing replenisher

The same stabilizer as that in Example 1 was used.

This continuous processing was run with an automatic processor till the volume of the stabilizing replenisher fed reached three times the capacity of the stabilizing tank.

With the sample subjected to the continuous processing, the magenta density at the maximum density portion was measured. After keeping the sample for 2 weeks at 75.degree. C. and 20% relative humidity, its maximum magenta density was measured again to calculate a fading rate of the dye.

Further, the sample processed as above was checked for backside stains and flaws as well. In addition, the solution in the second stabilizing tank was stored at 25.degree. C. in a beaker having a 50-cm.sup.2 opening to determine the residual concentration of a compound expressed by Formula (I) or a comparative compound. The results are shown in Table 7.

In the column of backside stains in Table 7, A indicates no backside stains occurred, B slight backside stains were observed, C obvious backside stains were observed, and D intolerably heavy backside stains were observed.

In the column of flaws in Table 7, A indicates no flaws occurred at all, B flaws occurred very rarely, C flaws occurred at times, and D flaws occurred on most film samples.

As apparent from the results in Tables 7 and 8, use of formaldehyde in large amounts, through it exerts no adverse effect on the fading rate, causes backside stains and flaws and lowers the residual formaldehyde concentration. Use of conventional substitutes for formaldehyde deteriorates the fading rate under low humidity conditions, causes backside stains and flaws, and lowers the residual concentration. On the other hand, use of the compounds of the invention gives excellent fading rates, particularly under low humidity conditions, and produces excellent results in backside stains and flaws as well as in residual concentrations of the compounds expressed by Formula (I). Example 4

The same procedure as in Example 3 was repeated, except that the stabilizer composition was changed as shown below:

Water was added to make 1 liter, then the pH was adjusted to 8.5 with sodium hydroxide or sulfuric acid.

The fading rate was evaluated in the same manner as in Example 3. Further, the solution in the second stabilizing tank was stored at 50.degree. C. for 1 week in a beaker having an opening area of 10 cm.sup.2 /l to observe formation of oily precipitates. The results are shown in Table 9.

The same procedure as that in Example 2 was repeated, except that 0.05 mol/l each of conventional sulfite-ion-releasing compounds were added to the stabilizer used in Experiment No. 2-31 of Example 3. The magenta fading rate and the backside stain were much the same as those in Example 2, but the preservability of the stabilizer (days till sulfur or sulfides begin precipitating) was increased by about 50%.

Stabilizer and stabilizing replenisher The same stabilizers as those in Experiment Nos. 2-1 to 2-33 of Example 3.

An evaluation made in a similar manner as in Example 3 gave much the same results as in Example 2. The working environment was good and free from unpleasant odors of ammonia and acetic acid.

Besides the effect of the invention, the bleach fog was decreased by 0.01 to 0.03 (transmitted densities of B, G and R) and the desilverizing property was improved by use of the processing solutions free from ammonia and acetic acid.

Example 9

An evaluation was made, in a similar manner as in Example 2, using the same silver halide color light-sensitive material as in Example 3 except that one of the following compounds (BAG 1 to BAG 3) was added in the first layer (antihalation layer) in an amount of 0.015 g/m.sup.2. The desilverizing property and the fading rate were improved, other properties were about the same as those in Example 2. ##STR43##

Example 10

An evaluation was made as in Example 1 by use of a stabilizer obtained by removing the antiseptic, 1,2-benzisothiazoline-3-one, from the stabilizer used in Example 1 and stabilizers prepared by replacing 1,2-benzisothiazoline-3-one with benzotriazole or o-phenylphenol and using water deionized with an ion exchange resin (having both strong basicity and strong acidity) to a salt content of magnesium 1.0 ppm and calcium 1.5 ppm. With the stabilizer containing no antiseptic, the period till sulfur or sulfides precipitated was decreased by 2 or 3 days.

This indicates the necessity of an antiseptic in storing the solution. The stabilizers using the other antiseptics or the deionized water exhibited about the same tendency as the stabilizer containing 1,2-benzisothiazoline-3-one.

The following concentrated stabilizer composition (concentrated solution) was prepared.

______________________________________1,2-Benzisothiazoline-3-one 0.05 gSurfactant (exemplified compound SU-5) 0.5 gCompound represented by Formula (I) or 2.5 gcomparative compound (shown in Table 6)Compound represented by Formula (II) or 8.0 gcomparative compound (shown in Table 6)______________________________________

The pH was adjusted to 9.5 with 40% aqueous solution of KOH. The degree of concentration is shown in Table 10. After preparation, each sample was evaluated in the same manner as in Example 2.

The concentrated composition and its usage are described below. In preparing a replenisher and a ready-to-use processing solution for silver halide color photography, concentrated solutions (or concentrated composition) for them are firstly prepared in general and diluted with water when used. Therefore, the concentration of a concentrated composition for a replenisher is usually 1.5 to 1,000 times as high as that of the objective replenisher. "The degree of concentration of a concentrated composition" means the concentration ratio of a concentrated composition to a composition in a replenisher. In a desirable embodiment of the invention, the degree of concentration is preferably not more than 350, especially not more than 300.
