Description

[Detailed description of the invention]

The present invention relates to color development processing of silver halide color photographic light-sensitive materials, and more specifically, the present invention relates to color development processing of silver halide color photographic light-sensitive materials, and more specifically, the enhancement of contrast in photographic performance caused by acceleration of physical development with thiosulfate ions and processing in the presence of high concentrations of bromide ions. The present invention relates to an improved development processing method in which deterioration of the fluorescent whitening agent is reduced when the color developing solution contains the fluorescent whitening agent. Processing of silver halide color photographic materials basically consists of two steps: color development and desilvering, in addition to which additional processing steps are added, such as black-and-white first development, stop processing, and stabilization processing. Silver halide exposed to light during color development is reduced to silver and at the same time oxidized aromatic primary
The grade amine developing agent reacts with the coupler to form a dye. During this process, halogen ions generated by decomposition of silver halide are eluted and accumulated in the developer. Additionally, components such as inhibitors contained in silver halide photographic materials are also eluted and accumulated during color development. In the desilvering step, silver produced by development is bleached with an oxidizing agent, and then all silver salts are removed from the photographic material as soluble silver salts with a fixing agent. A single-bath bleaching method is also known in which the bleaching step and the fixing step are performed simultaneously. As mentioned above, development inhibitors accumulate in color developing solutions when photographic light-sensitive materials are developed, but on the other hand, color developing agents and benzyl alcohol are consumed or accumulated in the photographic light-sensitive materials and taken out. The component concentration of decreases. Therefore, in a development method in which a large amount of silver halide photographic light-sensitive material is continuously processed using an automatic processor or the like, the components of the color developer are kept at a constant concentration in order to avoid changes in the development finish characteristics due to changes in component concentration. A means is needed to keep it within range. As such a method, a method of replenishing a so-called replenisher is usually used to replenish the missing components and dilute the increasing components. Since replenishment of this replenisher inevitably results in a large amount of overflow, which is discarded, this method poses a major economic and pollution problem. Therefore, in recent years, in order to reduce the overflow liquid, the so-called concentrated and low replenishment method, in which the replenisher is concentrated and refilled in small amounts, has been widely used.
Another method has been proposed and put into practical use by adding a regenerating agent to the overflow liquid and using it again as a replenisher. All of these methods substantially reduce the amount of replenishment, and if the amount of replenishment is extremely reduced, the concentration of the organic inhibitor and halogen ions eluted into the developer will increase. An increase in the halogen ion concentration causes the problem of high contrast due to suppression of the development reaction and further suppression of the legs of the characteristic curve. In order to avoid this, a method has been proposed in which halogen ions are removed from the overflow liquid and a regenerating agent is added to supplement the missing components to regenerate it into a replenisher. However, it would be more desirable if the process could be performed at a high halogen ion concentration without removing halogen ions, and in the case of removing halogen ions, the higher the halogen concentration, the higher the halogen ion removal efficiency. If the performance problem is resolved, it is desirable to use a tank solution with a high halogen ion concentration. Furthermore, in low replenishment processing in which the replenishment amount is reduced, another problem is an increase in contamination and accumulation of other processing liquid components. This is because the rate at which the tank liquid is replaced with replenisher becomes lower due to the decrease in the amount of replenishment, and also because the period of use of the liquid becomes longer. Contamination with other processing solutions is so-called back contamination, in which processing solution components after development are brought into the color developer by splashes of neighboring processing solutions in the processing machine, transport leaders, belts, film hangers, etc. caused by. Among these contaminant components that accumulate, thiosulfate ion, which is a fixing agent, accelerates development, and in particular accelerates the shoulder portion of the photographic characteristic curve, resulting in a remarkable increase in contrast. In addition, increased contamination of metal salts as bleaching agents, especially ferric salts, accelerates the decomposition of hydroxylamine as a preservative and generates ammonia ions. This decomposition reaction is significantly accelerated at temperatures above 33°C. The generation of ammonia ions, like thiosulfate ions, has the disadvantage of accelerating physical development and increasing contrast. Recently, in color paper processing, fluorescent brighteners have been added during color development and bleach-fix solutions to omit stabilization processing in order to speed up processing and simplify processing baths. Generally, a whitening effect is applied. In this case as well, there is a drawback that if the liquid retention period is prolonged due to a low replenishment amount, the fluorescent whitening agent, which is sensitive to light and heat, decomposes and the whitening effect is almost lost. Particularly when using diaminostilbene type brighteners, this decomposition is significantly influenced by the tank liquid renewal rate. Therefore, in order to improve economy and reduce environmental pollution, there is a strong desire to develop a color developing solution that maintains constant photographic performance even when the amount of replenishment is reduced, and whose active ingredients do not decompose even if the processing solution is used for a long time. The current situation is what is desired. The purpose of the present invention is to improve the above-mentioned drawbacks that occur when continuous processing is performed with a low replenishment amount using a color developing solution, and to develop a halogenated solution that can maintain appropriate photographic performance and processing performance of the solution over a long period of time. An object of the present invention is to provide a method for developing a silver color photographic material. Other objects of the invention will become apparent from the description. The object of the present invention is to provide a continuous processing method for silver halide color photographic materials using an automatic processor,
The developer contains at least 1 g or more of polyethylene glycol expressed by the following general formula [] with an average molecular weight of 1000 to 6000 and at least 0.01 g per 1 portion.
mol of bromide ion in the presence of a paraphenylenediamine color developing agent at a processing temperature of 33
This is achieved by a method for processing silver halide color photographic materials in which processing is performed at temperatures above .degree. General formula [] HO(CH ₂ CH ₂ O) _o CH ₂ CH ₂ OH [In the formula, n represents a positive integer. ] Generally, in the development reaction when bromide ions are present at a high concentration, the suppressing effect at the legs of the characteristic curve is greater than at the shoulders, so that the photographic characteristics become high contrast (hereinafter referred to as high gamma). Further, even if the amount of thiosulfate ion is extremely small, it promotes the development of the shoulder area, which is susceptible to physical development, and increases the gamma. The presence of ammonia ions generated by the decomposition of hydroxylamine also increases gamma for the same reason as the presence of thiosulfate ions. Apart from this, bistriazinylaminostilbene-based fluorescent brighteners, which are often added to color developing solutions for color paper, have the property of easily isomerizing when exposed to light and losing their brightening effect. . All of the above-mentioned developments inevitably occur in systems where the amount of replenishment of the color developing solution is small; however, as a result of various studies, the present inventors have found that the general formula with an average molecular weight of 1000 to 6000 used in the present invention [ ] (hereinafter referred to as the polyethylene glycol of the present invention)
However, when the concentration of bromide ions is high, especially when it contains 0.01 mole or more as bromide ions, the gamma of the characteristic curve is lowered, and the gamma value is kept constant at an appropriate value regardless of the concentration of bromide ions. , thiosulfate ions are mixed into the developer solution at a rate of about 10 mg when processed continuously in a normal processing machine. If the hanger is not washed properly, up to about 20 mg/ml may be mixed in. It has been found that, similarly to the case of bromide ions, by incorporating the polyethylene glycol of the present invention into the treatment solution, it is possible to suppress a significant increase in gamma and maintain a constant gamma value at an appropriate level. Particularly in this case, the higher the bromide ion concentration, the greater the gamma-lowering effect, and the higher the bromide ion concentration, and the greater the thiosulfate ion content, the greater the gamma-lowering effect of polyethylene glycol. The fact that such photographic performance was maintained was completely unexpected and surprising considering the performance of polyethylene glycol, which is known as a development accelerator in ordinary color developing solutions. Furthermore, ferric ion, which is a bleaching agent, is 1 to 5 ppm.
The decomposition of hydroxylamine due to the catalytic action of these iron ions is particularly accelerated at high temperatures (above 33°C), and the ammonia ions generated by this decomposition increase gamma; It was found that the addition of the polyethylene glycol of the invention did not increase gamma at all and significantly suppressed the occurrence of fog. In this case as well, it was found that these effects increased synergistically when the bromide ion content was high. By adding the polyethylene glycol of the present invention to a color developing solution containing a bistriazinyldiaminostilbene-based fluorescent brightener, it prevents the isomerization of the fluorescent brightener to the cis form and stabilizes it for a long period of time. It has also been found that the whitening effect can be maintained. This effect is particularly pronounced during high-temperature treatment. Further, as a preferred embodiment of the method of the present invention, the development method using an automatic processor is such that immediately after color development, processing is performed with a processing solution containing a thiosulfate (for example, a fixing solution, a bleach-fixing solution, a bleaching solution, etc.). Can be mentioned. In such embodiments, the method of the present invention is particularly effective in preventing the occurrence of fog due to physical development due to the presence of thiosulfates. Sources of bromide ions contained in the developer used in the present invention include hydrobromic acid, sodium bromide, potassium bromide, sodium bromide, etc. Ammonium bromide is also used in some cases. Is possible. The concentration of bromide ion used is at least 0.01 mole per bromide ion, preferably 0.011 mole or more, particularly preferably 0.0125 mole or more. However, too high a concentration of bromine ions greatly inhibits the development reaction, so bromine ions are less than 0.25 mol per 1 mol, preferably 1 mol per bromine ion.
0.125 mol or less, particularly preferably 0.125 mol per
Concentrations below 0.0625 molar are suitable. The polyethylene glycol of the present invention is a compound represented by the following formula, HO(CH ₂ CH ₂ O) - _o CH ₂ CH ₂ OH (n represents a positive integer).

These color developing agents are generally used in concentrations of from about 0.1 g to about 60 g per color developer, more preferably from about 1 g to about 15 g per color developer. Further, the above color developing agents may be used alone or in combination of two or more.

The pH value of the developer thus adjusted is 7 or more, and is usually used at a pH value of 9.5 to 13. The treatment temperature is 33°C or higher, preferably 35°C to 60°C.

Those described in the specification of Japanese Patent Application No. 54-82175 etc. can be applied. The color developing agent contained in the light-sensitive material can be contained in any layer containing a hydrophilic colloid on the same side as the photosensitive silver halide emulsion on the surface of the support. Such layers include, for example, a protective layer, a photosensitive layer containing a silver halide emulsion, a non-photosensitive intermediate layer, and an image receiving layer for color diffusion transfer (which also contains an oxidizing agent).
However, it is preferable to include them in the photosensitive layer or in the upper and/or lower hydrophilic colloid layer adjacent to the photosensitive layer. The method for incorporating a color developing agent into a hydrophilic colloid aqueous solution is as follows. That is, when the compound of the present invention is hydrophilic, its aqueous solution (which may contain a readily water-soluble solvent) can be added to the hydrophilic colloid aqueous solution. In addition, when the color developing agent is hydrophobic (poorly soluble in water), latex dispersion method and oil-in-water emulsion dispersion method are particularly effective.
For these, conventionally known methods are available, such as Japanese Patent Application Laid-open Nos. 49-74538, 51-59943, and 54-32552, Research Disclosure, 1976, 8
The method described in Month No. 14850, pages 77 to 79 can be applied. In order to improve the instability caused by the inclusion of color developing agents, compounds conventionally used as cross-oxidizing agents in light-sensitive materials may be used. For example, black and white developing agents, particularly preferred are 3
-Pyrazolidone compounds and hydroquinone compounds are useful. Metal salts described in US Pat. No. 3,719,492 may also be used to stabilize color developing agents. Further, polyvinylpyrrolidone can also be included in these photosensitive materials. When a color developing agent is incorporated into a light-sensitive material, it is not necessary to include the color developing agent in the developer. Next, silver halide color photographic materials that can be used in the present invention will be described. A silver halide photosensitive material consists of a support (for example, a glass plate, polyethylene terephthalate, cellulose acetate film, baryta paper, polymer-coated paper, etc.) and at least one silver halide emulsion layer coated thereon. The silver halide emulsion layer may be coated on both sides of the support, and may have a back layer, antihalation layer, intermediate layer, fitter layer, surface protection layer, etc., if necessary. Silver halide emulsions are made by combining silver halides such as silver chloride, silver iodide, silver bromide, silver chlorobromide, silver iodobromide, silver chloroiodobromide with hydrophilic colloids (e.g. gelatin, modified gelatin, casein, carboxymethylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, etc.). A silver halide emulsion is prepared by combining a water-soluble silver salt (e.g. silver nitrate) and a water-soluble halide salt in the presence of water and a hydrophilic colloid by a method commonly practiced in the art (e.g. single-jet method, double-jet method). It is manufactured by mixing it with water and performing physical heat formation and, if necessary, chemical heat formation with sulfur compounds, gold compounds, etc. The silver halide emulsion contains at least one of all known oil-soluble couplers, and the coupler solvents used include dibutyl phthalate, dioctyl phthalate, dimethyl phthalate, and all other organic solvents that can dissolve oil-soluble couplers. I can do it. Silver halide emulsions may contain spectral sensitizers (cyanine dyes,
merocyanine dye, etc.), stabilizers (e.g., 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene, benzotriazole, 5-nitrobenzimidazole, etc.), hardeners (e.g., formalin, glyoxal, 2 -hydroxy-4,
6-dichloro-S-triazine, mucochloric acid, etc.), coating aids (e.g. saponin, sodium lauryl sulfate, polyethylene oxide, etc.), polymer latexes, polyvinylpyrrolidone, etc. can be added. Regarding other developing solutions, methods for producing silver halide photosensitive materials, additives, etc., please refer to Protect Licensing Index, Vol. 92, pp. 107-110 (1971).
You can refer to the description in December). The processing method of the present invention using the developer used in the present invention is applicable to color photosensitive materials such as color negative film, color paper, color positive film, color reversal film for slides, color reversal film for movies, color reversal film for TV, and color X-ray for medical use. It can be used not only for general silver halide color photographic light-sensitive materials such as film, but also for color photographic light-sensitive materials made by silver dye bleaching method and direct positive silver halide color photographic light-sensitive materials of internal latent image type or latent image destruction type. . The method of processing color light-sensitive materials according to the present invention includes all methods of processing color light-sensitive materials that include a step of color development using a processing solution having color-forming ability. A specific representative example of the preferable treatment method includes the following steps. However, the processing method of the present invention is not limited to this.

[Table] As can be seen from the results in Table 2, when treated with a comparative color developer other than that of the present invention, potassium bromide and thiosulfate ion concentration increased significantly in both cases. Gamma fluctuates and the value also increases, resulting in high contrast. or,
Even if polyethylene glycols other than those of the present invention are used, this high contrast cannot be prevented. Further, although a developer having a low potassium bromide concentration and containing no thiosulfate ions has a low gamma value to begin with, the addition of polyethylene glycol increases the gamma value. On the other hand, when the polyethylene glycol according to the present invention is used in the amount according to the present invention, even if the concentration of potassium bromide changes or the mixing of thiosulfate ions increases, the gamma does not increase significantly and remains constant. It can be maintained within the range. In particular, even when the concentrations of potassium bromide and thiosulfate ions were simultaneously increased, no significant increase in gamma was observed, indicating that gamma could be maintained at an almost constant level. Furthermore, this thiosulfate ion is approximately 7.5% when processed with an automatic processor using an endless belt.
It was present at a level of mg/mg. Example 2 The same color paper as in Example-1 was exposed and processed using the same processing steps. The same bleach-fix solution as in Example-1 was used. The following color developing solution was used as a base solution, and the compounds shown in Table 3 were added to it, and the pH was adjusted to 1 with water to make the pH 10.2. 1 Stored in a narrow-mouthed glass bottle at 38°C without a stopper, developed and processed 4 hours after adjustment, 4 days after storage, and 1 week after storage. The brightening effect was observed by measuring the spectral reflectance (spectral reflectance). Furthermore, we measured gamma from photographic density 0.8 to density 1.8 and compared changes in contrast. The results are shown in Table-4.

[Table] As can be seen from the results in Table 4, developer solutions C to D containing polyethylene glycol, which is the compound of the present invention, showed no decrease in spectral reflectance due to storage over time, and the photographic properties did not change in any case. Gamma does not change and maintains a constant value. In comparison, it can be seen that in the developing solutions other than those of the present invention, not only does the gamma significantly increase simply by mixing the bleach-fixing solution, but also the gamma further increases upon storage. In addition, when we conducted a fog test by performing a developing process for twice the time as the standard process, which is not listed in Table 4, we found that with developers A and B, there was a significant increase in fog due to storage of the developer. However, developers C to E showed no increase in fog and were stable. This indicates that the compound of the present invention significantly suppresses physical development due to ammonia ions generated due to decomposition of hydroxylamine in the developer over time, and also prevents deterioration of the fluorescent brightener. Recognize. The storage temperature for this storage over time is 25℃, 30℃, 35℃,
When the storage temperature was changed to 40°C, the increase in gamma due to storage was very small for all the developers at storage temperatures below 30°C, and at temperatures above 35°C, only developers A and B showed a significant increase in gamma. Example 3 Using developer solutions A and D of Example 2, Example 2
Continuous processing was performed using an automatic processor RPE202 manufactured by Noritsu Kozai Co., Ltd. using the same processing method as above. The processing solution was replenished only for color development, and 1000 m of Sakura Color Paper 8.9 cm wide roll paper was continuously processed while replenishing only the amount of the solution taken out. As in Example 1, the gamma of developer A increased because potassium bromide and bleach-fix components were brought in and increased by the endless belt during processing, but the gamma value of developer D remained constant.
