Description

[Detailed description of the invention]

The present invention relates to a method for processing a silver halide color photographic material, and more particularly to a method for processing a silver halide color photographic material continuously with a bleach-fix solution in an automatic processor. Generally, in order to obtain a color image by continuously processing an imagewise exposed silver halide color photographic light-sensitive material using an automatic processor, after the color development step, a processing solution having bleaching ability is used to remove the generated metallic silver. A step of processing is provided. Bleaching solutions and bleach-fixing solutions are known as processing solutions having bleaching ability. When a bleaching solution is used, a step of fixing the silver halide with a fixing agent is usually added after the bleaching step, but with a bleach-fixing solution, bleaching and fixing are performed in one step. In the bleaching step or bleach-fixing step, components of the processing solution from the previous step that are brought in adhering to the silver halide color photographic light-sensitive material, composition components consumed by bleaching or bleach-fixing, and silver halide color photographic light-sensitive materials are In order to always maintain a constant concentration of components eluted from the material and accumulated in the bleach or bleach-fix solution in the bleach or bleach-fix solution, a suitable amount of a bleach or bleach-fix replenisher having an appropriate composition is replenished. Inorganic oxidizing agents such as red blood salts and dichromates are widely used as oxidizing agents for bleaching image silver in processing solutions that have bleaching ability in processing silver halide color photographic light-sensitive materials. . However, several serious drawbacks have been pointed out to processing solutions containing these inorganic oxidizing agents and having bleaching ability. For example, red blood salt and dichromate have relatively good bleaching power for image silver, but there is a risk that they will decompose when exposed to light and produce cyanide ions and hexavalent chromium ions that are harmful to the human body.
It has unfavorable properties in terms of pollution prevention. In addition, because these oxidizing agents have extremely strong oxidizing power, it is difficult to coexist with silver halide solubilizing agents such as thiosulfates in the same processing solution, making it difficult to use these oxidizing agents in bleach-fixing baths. is almost impossible, which makes it difficult to achieve the goal of speeding up and simplifying the process. Furthermore, processing liquids containing these inorganic oxidizing agents have the disadvantage that it is difficult to reuse the waste liquid after treatment without discarding it. On the other hand, metal complex salts of organic acids, such as aminopolycarboxylic acid metal complex salts, are used as oxidizing agents, as they have fewer pollution problems and meet the demands of speeding up and simplifying treatment, and enabling the reuse of waste liquids. In recent years, treatment solutions have come to be used. However, processing solutions using metal complex salts of organic acids have a slow oxidizing power, so they have the disadvantage that the bleaching rate (oxidation rate) of image silver (metallic silver) formed in the development process is slow. . In general, in neutral or alkaline environments, the oxidizing power of metal complex salts of organic acids decreases due to alkaline hydrolysis reactions and dimerization reactions, and the diffusivity decreases, resulting in a significant decrease in silver bleaching power. Are known. Therefore, in order to increase the silver bleaching ability of a treatment solution using a metal complex salt of an organic acid, it is sufficient to lower the pH of the treatment solution and use it in an acidic range. As a result of promoting the reduction reaction of coloring dyes, particularly cyan dyes, by reduced forms of acid metal complex salts and converting them into leuco, a serious problem arises in that dye images take on a reddish tinge. Furthermore, a decrease in pH is caused by an increase in the oxidizing power of the metal complex salt of an organic acid in the bleach-fix solution, which reduces the rate of redox reaction with the fixing agent and sulfite ions used as a preservative for the fixing agent. It is known that the storage stability of the bleach-fix solution decreases as a result of the disproportionation reaction caused by protons of thiosulfate ion commonly used as a fixing agent. For this reason, the bleaching solution or bleach-fixing solution is practically used within the range of PH6 to PH8. Furthermore, when silver halide color photographic light-sensitive materials are continuously processed using an automatic processor, and when bleaching or bleach-fixing is performed directly after the color development process, the color developer may adhere to the light-sensitive material and cause bleaching or bleaching. Significant concentrations of color developer accumulate by being carried into the bleach-fix solution. Under these conditions, the bleach or bleach-fix solution should be
When processing while maintaining the temperature of 6 to 8, the metal complex salt of the organic acid is reduced by reacting with the reducing component of the mixed and accumulated color developer, and a reduced form of the metal complex salt of the organic acid is produced. As the bleaching power decreases,
The above-mentioned leucoization phenomenon also becomes more likely to occur. Also, PH
Bleaching or bleach-fixing solutions with a concentration of less than 6 have the disadvantage that leucoization tends to occur even though the silver bleaching ability is high. On the other hand, although great efforts have been made to develop bleaching accelerators to increase the silver bleaching power of bleaching solutions or bleach-fixing solutions containing metal complex salts of organic acids, satisfactory results have not yet been obtained. That is the reality. In addition, in order to eliminate the above-mentioned leuco-formation phenomenon, there have been cases in which an oxidation bath containing red blood salt, etc. is provided to develop the leuco-formed color pigment after bleaching or bleach-fixing. This is not desirable because it goes against the demands of speeding up and simplifying the processing, and there is also the risk of causing pollution. Therefore, the first object of the present invention is to maintain a high silver bleaching ability during continuous color development and direct bleach-fixing processing using an automatic processor. Our goal is to provide the following. A second object of the present invention is to provide continuous bleach-fixing processing from color development to direct bleach-fixing using an automatic processor.
It is an object of the present invention to provide a method for processing a silver halide color photographic light-sensitive material in which the phenomenon of dye leucoization is not observed. A third object of the present invention is a method for processing a silver halide color photographic light-sensitive material that can always maintain a stable bleach-fixing ability during continuous color development and direct bleach-fixing using an automatic processor. Our goal is to provide the following. The object of the present invention is to directly process an imagewise exposed silver halide color photographic light-sensitive material by an automatic processor from color development containing an aromatic primary amine color developing agent to bleach-fixing containing a metal complex salt of an organic acid. A silver halide treatment method in which the bleach-fix solution contains a color developing solution of 30% or more, and the bleach-fix solution has a pH of 4.5 to 5.5. This is achieved by a method for processing color photographic materials. What is a bleach-fix solution containing a metal complex salt of an organic acid?
It refers to a processing solution that has the ability to bleach and fix metal salts produced in the color development process of silver halide color photographic materials. The present invention is particularly suitable for bleach-fixing processes. Generally, when color development and direct bleach-fixing are carried out continuously using an automatic processor, the amount of color developer that accumulates in the bleach-fix solution due to adhesion to the photographic light-sensitive material is It can be set arbitrarily depending on the degree of squeezing immediately after and the amount of bleach-fixing replenisher. However, the color developing solution brought into the bleach-fix solution is
By continuously treating the bleach-fix solution at 30% or more while maintaining the pH of the bleach-fix solution at 4.5 to 5.5, it is possible to maintain high silver bleaching power and reduce the occurrence of leucoization, which further improves bleaching properties. It is not known at all that it does not reduce the liquid stability of the fixer. Although this phenomenon has not yet been fully elucidated, it is expected that under these conditions, the color developing agent present in the bleach-fix solution, especially the aromatic primary amine color developing agent, acts effectively. . Even if the color developer in the bleach-fix solution is 30% or more, if the pH of the bleach-fix solution is less than 4.5, a leuco conversion phenomenon occurs and the stability of the bleach-fix solution decreases, causing the pH of the bleach-fix solution to drop below 5.5. If it is exceeded, a leucoization phenomenon occurs. Furthermore, even if the pH of the bleach-fix solution is 4.5 to 5.5,
If the content of the color developer in the bleach-fix solution is less than 30%, a leuco conversion phenomenon occurs and the stability of the bleach-fix solution decreases. The metal complex salt of an organic acid in the present invention has the effect of oxidizing metallic silver produced by development and converting it into silver halide, and its structure is based on an organic acid such as aminopolycarboxylic acid or oxalic acid or citric acid. It is coordinated with metal ions such as iron, cobalt, and copper.
