Description
FIELD OF THE INVENTION
The present invention relates to a method for processing a transparent silver halide color photographic material, hereinafter referred to a color light-sensitive material for simplifying, and a product thereof produced by processing the transparent silver halide color photographic material, particularly relates to a method for processing a transparent silver halide color photographic material and a product thereof by which a suitable print can be obtained with no influence on the image density even when coated silver halide is remained in the processed transparent silver halide color photographic material. The invention further related to a method for processing a transparent thereof by which no problem is caused on the storage ability of image and a suitable print can he obtained even when coated silver halide is remained in the processed transparent silver halide color photographic material.
BACKGROUND OF THE INVENTION
London Treaty has been entered according to the trend of protection of environment of the earth, and dumping waste photographic processing liquids into ocean has been substantially prohibited. Accordingly, efforts to reduce the photographic waste liquids have been made in the field of photography. Regarding the fixing solution, reduction of the waste liquid and that of the replenishing amount have been studied as shown in Japanese Patent Publication Open to Public Inspection (JP O.P.I.) no. 8-201997.
Besides, increasing in the sensitivity of color film has been progressed accompanied with a prompt growth of demand for a film with lens and spread of a camera with a zoom function. Such the high speed film usually has a high silver iodide content and coated silver amount. As a result of that, the load on the treating process, particularly on the bleaching process, has become a problem.
Furthermore, an ammonium salt such as ammonium thiosulfate and ammonium thiocyanate is used as a fixing agent to be used in the fixing solution from the viewpoint of a clearing time. However, degradation of working environment has been made since such the ammonium slat forms ammonia gas when the pH of the fixing solution is exceeded to 7, and the ammonia gas drifts around the automatic processor and causes displeasure order. Particularly, the problem is made serious if the automatic processor is installed in a badly ventilated place such as a foods store in a basement of a building. The fixing tends to made insufficient when a receipt in which the amount of ammonium salt is reduced as small as possible is applied as a countermeasure of such the problem.
Moreover, the fixing solution is with circulation in the treating tang of the automatic processor for purposes of uniforming the temperature, removing dust in the tank and stirring the solution. However, contact of the fixing solution with air is accelerated by the circulation and the fixing solution tends to be oxidized. The oxidation of the fixing solution causes formation of sulfurized substance and a serious problem is raised when the sulfurized substance is adhered to the light-sensitive material. Such the problem is made more serious when the replenishing amount is reduced. An insufficient fixation is caused when the circulation is reduced as a countermeasure to such the problem.
In the silver removing process in which silver halide and metallic silver in the light-sensitive material is removed into a processing solution, silver halide tends to be remained in the light-sensitive material in a form of unfixed silver which causes insufficient fixation. Such the insufficient fixation is caused by raising the accumulated silver amount in the processing solution caused by reduction of the replenishing amount or processing a light sensitive material having a high coated silver amount, the use of a fixing solution having a reduced ammonium ion content, and the use of an automatic processor with reduced circulation.
When the insufficient fixation is formed in a color light-sensitive material, a color remaining stain is formed since a dye is remained accompanied with a lot of silver remaining in the light-sensitive material. A serious problem such as change in the tone of the light-sensitive material and degradation in the image quality is raised at the print of image when such the color stain is formed. It is usual in a mini-lab that various level of conditions (channels) suited for various light-sensitive materials are previously set using a standard negative film and the printing of a kind of film is performed by using the channel suited to such the film. For such the procedure, it is necessary that the negative is constantly finished. Accordingly, color prints having a constant quality cannot be obtained when the color stain is formed since the density of the negative is varied. The insufficient fixation usually tends to be formed ununiformly. In such the case, the quality of print is considerably degraded.
On the other hand, a method is disclosed in JP O.P.I. No. 8-29930 in which the majority of coated silver is remained in the part of undeveloped part other than image formed part of a monochromatic light-sensitive material. In the monochromatic light-sensitive material, however, such the problem is not made serious since the problem of the color stain and that prints having a constant quality is prepared by a printer are hardly raised in the monochromatic light-sensitive material.
It is difficult to solve the above-mentioned problems regarding the fixing process of color light-sensitive material since in the color light-sensitive material, the reduction of replenishing of the fixing process, the reduction of the ratio of ammonium ion and the reduction of the circulation in an automatic processor are difficult because it is necessary to perfectly remove the silver hailed from the light-sensitive material from the viewpoint of the color stain.
Recently, a high-speed color negative film having a high amount of coated silver is frequently used, and the replenishing in the fixing process is reduced. Therefore, silver halide tends to be remained in a form of unfixed silver in the light-sensitive material and tend to cause an insufficient fixation. A large amount of silver halide is remained in the light-sensitive material when the insufficient fixation is occurred, and the silver salt is changed to black silver by heat, moisture of light, or the silver halide is reacted by thiosulfate remained in the light-sensitive material to form silver sulfide after the processing. When the black silver or silver sulfide is formed in a negative film, problems such as change in the tone of the light-sensitive material and degradation in the image quality are raised after storage, and serious problems are caused at the printing of the image in the future.
Moreover, a demand of reducing replenishing amount is also raised in the processing of a color paper, and an insufficient fixation tends to be occurred when the replenishing is reduced, and the degradation of storage ability image is feared.
As above-mentioned, it has been common knowledge that silver halide in light-sensitive material is completely removed for reducing the replenishment in the fixing process. Besides, the storage ability of image can be improved by the invention in which unfixed silver is stabilized by the use of specific compound and silver salt is positively remained in the light-sensitive material.
On the other hand, a method is disclosed in JP O.P.I. No. 8-29930 in which the majority of coated silver is remained in the part of undeveloped part other than image formed part of a monochromatic light-sensitive material. However, the problem of the storage ability of dye image at the image forming portion of color light-sensitive material is not raised since the image is formed by silver, not dye, in the monochromatic light-sensitive material. Accordingly, the problem to be solved in this publication is quite different from the invention, and there is no description suggesting the invention in the publication.
The above-mentioned insufficient fixation of negative film tends to be unevenly formed on the film, and a serious problem is raised since the unevenness on the negative is printed on the color paper when the negative is printed on the paper. It has been found by the inventors that a suitable print can he obtained, even when the silver salt is remained in the light-sensitive material, by removing the influence of the silver salt on the transmitting light by the use of the compound of the invention. The problem of the unevenness insufficient fixation also can be soled.

Thus obtained dispersion is added to a coating liquid containing a hydrophilic colloid substance, and the liquid is coated on a support or on the layer such as a silver halide emulsion layer coated on a support.

EXAMPLES
Example 1
(Preparation method of light-sensitive material)
An emulsion of seed crystal was prepared in the following manner.
A silver nitrate aqueous solution (1.161 moles) and a solution of mixture of potassium bromide and potassium iodide (content of potassium iodide of 2 mole-%) were added to the following Solution A held at 35.degree. C. by a double-jet method spending 2 minutes using a stirrer mixing apparatus described in Japanese Patent Nos. 58-58288 and 58-58289 while the silver electrode potential (measured by a silver ion selecting electrode using a saturated silver-silver chloride electrode as a comparative electrode) was maintained at 0 mV to form nuclei. Then the temperature was raised by 60.degree. C. spending 60 minutes, and pH was adjusted to 5.0 by an aqueous solution of sodium carbonate. To the emulsion, an aqueous silver nitrate solution (5.902 moles) and an aqueous solution of mixture of potassium bromide and potassium iodide (potassium iodide of 2 mole-% were added by a double-jet method spending 42 minutes while the silver electrode potential was maintained at 9 mV. After the addition, the emulsion was desalted and washed by an usual flocculation method in the course of lowering the temperature to 40.degree. C.

Preparation fine grain silver iodide emulsion SMC-1
Two liters of an aqueous solution containing 7.06 moles of silver nitrate and 2 liters of an aqueous solution containing 7.06 moles of potassium iodide were added to 5 liters of an aqueous solution containing 6.0% by weight of gelatin and 0.06 moles of potassium iodide spending 10 minutes while vigorously stirring. In the course of addition, the pH was controlled at 2.0 using nitric acid and the temperature was held at 40.degree. C. After formation of grains, pH was adjusted to 5.0 by an aqueous solution of sodium carbonate. The average diameter of thus obtained silver iodide fine grains was 0.05 .mu.m. The emulsion was referred to SMC-1.
Preparation of Emulsion Em-1
Seven hundreds milliliters of an aqueous solution containing Seed Crystal Emulsion-1 in an amount corresponding to 0.178 moles, 0.5 ml of 10% methanol solution of HO(CH.sub.2 CH.sub.2 O).sub.m (CH(CH.sub.3)CH.sub.2 O).sub.19.8 (CH.sub.2 CH.sub.2 O).sub.n H (m+n=9.77) and 4.5% by weight of gelatin was maintained at 75.degree. C. and the pAg and pH are adjusted to 8.9 and 5.0, respectively. Grains were formed by the following procedure using a double-jet method while vigorously stirring the solution.
1) To the solution, 2.1 moles of aqueous solution of silver nitrate, 0.195 moles of SMC-1 and an aqueous solution of potassium bromide were added while the pAg and pH was maintained at 8.9 and 5.0, respectively.
2) Then 1.028 moles of aqueous solution of silver nitrate, 0.032 moles of SMC-1 and an aqueous solution of potassium bromide were added while the pAg and pH was maintained at 8.9 and 5.0, respectively.
In the course of the grain formation, the solutions were each added in a proper rate so that new nucleus was not formed and ostwald ripening was not proceeded. After completion of the addition, the emulsion was desalted and washed by an usual flocculation process at 40.degree. C. and redispersed by adding gelatin, and the pAg and pH thereof were adjusted to 8.1 and 8.5, respectively.
Thus obtained emulsion is an emulsion comprising tabular grains having a grain diameter (the length of a side of a cube having the same volume) of 0.65 .mu.m, an average aspect ratio of 7.2 and a halide composition shown in Table 7. The surface silver iodide content measured by the method described in this specification was 4.5 mole-%.
Sensitizing dyes SD-5, SD-6 and SD-7 were added to the above obtained Emulsion Em-1, and sodium thiosulfate, chloroauric acid, potassium thiocyanate, and a selenium sensitizer b-1 were added. Then the emulsion was chemically ripened so that the relation of fog and sensitivity was made optimum.
After completion of the chemical sensitization, a stabilizer ST-1 and a fog preventing agent AF-1 were added to the emulsion. The added amount of ST-1 was 1 g per mole of silver halide and that of AF-1 was 15 mg per mole of silver halide.
Thus chemically sensitized Em-A corresponding to Em-1 was prepared. ##STR8## <Preparation of multi-layer color photographic material>

Each of the solutions were charged to the automatic processor, and Color Negative Film LV400, manufactured by Konica Corp., was processed until the replenishing amount to the fixing tank was become 3 times of the volume of the fixing tank (10 liters) to bring the processing solution into the converged state. A scene was photographed by the above-prepared of multi-layer color photographic material Sample 101 with under-, normal- and over-exposure conditions. The sample was processed by the above-prepared converged processing solutions. Besides, a negative of Sample No.1 was refixed after the processing by the fixing solution for 90 seconds at 38.degree. C., washed for 3 minutes and dried to prepare a standard negative (completely desilvered negative). The level of the negative channel of a printer processor of NPS-858-J-A system, manufactured by Konica Corp., was set using the standard negative. Namely, a print having the same quality as a print printed through the standard negative can be obtained from a negative proceed by the same level processing as the standard negative. Prints were prepared from the light-sensitive materials each processed by each of the converged processing solution, respectively, using the such set channel. When the printed level of the print was not equal, the level was compensated. The compensated YMC density was shown in Table 1. It is considered that the level compensation within 10% is not problem in practical use.
The remaining silver amount and the transmission density at 650 nm were also measured.
Moreover, the processed light-sensitive materials were each refixed, rewashed and redried in the same manner as in the standard negative, and the difference of RMS granularity measure before and after the retreatment (.DELTA.RMS) was determined. The RSM granularity was measured by scanning the density of the portion to be measured by a micro densitometer having a scanning open area of 750 .mu.m.sup.2 (slit width of 10 .mu.m and slit length of 75 .mu.m). A value of 1000 times of standard deviation of the variation of density at 1000 or more sampling points was determined and the value was expressed by a relative value when the value of Sample No. 1 was set at 1.00. A smaller value of .DELTA.RMS corresponds to better property.
Thus obtained results are shown in Table 1.

Regarding Sample Nos. 1 to 3, the circulation amount in the fixing tank of the automatic processor was varied to control the remaining amount of silver in the light-sensitive material (Sample 1: 3 l/min., Sample 2: 5 l/min. and Sample 3: 6 l/min.). The other samples were all fixed at 3 l/minutes.
As is shown in the results in Table 1, the light-sensitive materials having the relation between the remaining amount of silver and the transmission absorbance at 650 nm is within the range of the invention (the constitution of the invention described in claims 1 and 7) each give a certain quality of print, and there is no problem in the levels of granularity compared with that of the standard negative. As above-mentioned, the light-sensitive material can be prepared by the invention (the constitution of the invention described in claims 1 and 7) which gives a satisfactory print quality even when the silver is not completely removed.
Example 2
Prints were prepared while compensating the printing condition in the same manner as in Sample Nos. 1 and 7 of Example 1 except that the replenishing amount of the fixing solution was changed as shown in Table 2 in the course of preparation of the converged processing solutions. .DELTA.RMS of each of the samples was measured and described in a relative value when that of comparative sample No. 1-1-1 was set at 1.00. Thus obtained results are shown in Table 2.
