Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an exposed silver halide color photographic light-sensitive material (
A development processing method (hereinafter simply referred to as processing) for developing, bleaching, and fixing color photosensitive materials (hereinafter referred to as color photosensitive materials), in particular, accelerates the bleaching action, shortens processing time, and performs sufficient bleaching to improve image quality. The present invention relates to an improved development processing method capable of forming good color photographic images.

(Prior Art) Generally, the basic steps in processing color photosensitive materials are a color development step and a desilvering step. That is, the exposed silver halide color photographic material is put into the color development step. The color developing agent reduces the silver halide to yield silver, and the oxidized color developing agent reacts with the color former to give a dye image.The color photographic material is then subjected to a desilvering process. Here, the silver produced in the previous step is oxidized by the action of an oxidizing agent (commonly called a bleaching agent), and then dissolved and removed by a silver ion complexing agent, commonly called a fixing agent. Only a dye image is produced in the photographic material that has gone through this process.In addition to the two basic steps of color development and desilvering mentioned above, the actual development process is carried out in order to maintain the photographic and physical quality of the image. It includes auxiliary processes such as improving the storage stability of images. Examples include a hardening bath to prevent excessive softening of the photosensitive layer during processing, a stop bath to effectively stop the development reaction, Examples include an image stabilizing bath for stabilizing the image and a film removal bath for removing the backing layer of the support.

In addition, the desilvering process mentioned above is carried out in two steps, with the bleaching bath and fixing bath being separate baths, and in other cases, the processing process is simplified for the purpose of speeding up processing and labor saving, and bleaching agent and fixing agent are used together. Sometimes it is carried out in one step using a bleach-fixing bath.

In recent years, there has been a demand for quick and simple processing and prevention of environmental pollution in color photographic materials.
ty complex salts (for example, aminopolycarphonic acid ferric ion complex salts, etc., especially iron ethylenediaminetetraacetate (Il
l) Bleaching treatment methods based mainly on complex salts are mainly used.

However, since ferric ion complex salts have a relatively small oxidizing power and a bleaching blade is insufficient, products using this as a bleaching agent are, for example, low-sensitivity silver halide color photographs based on silver chlorobromide emulsions. When bleaching or bleach-fixing the material, it is possible to achieve the desired purpose, but it is possible to achieve the desired purpose if the material is bleached or bleach-fixed. When processing silver halide color photographic materials, especially color reversal photographic materials and color negative photographic materials that use high silver content, the bleaching effect may be insufficient, resulting in poor desilvering or bleaching. The disadvantage is that it takes a long time to complete.

Furthermore, in color light-sensitive materials, sensitizing dyes are generally used for the purpose of color sensitization. In particular, when tabular grains with high silver or high aspect ratio are used with the aim of achieving high sensitivity, there is a problem that the sensitizing dye adsorbed on the silver halide surface inhibits the bleaching of the silver produced during development of the silver halide. arise.

Persulfates are known as bleaching agents other than ferric ion complex salts, and persulfates are usually used as a bleach solution by adding chloride. However, the disadvantage of bleaching solutions using persulfates is that they have a weaker bleaching edge than ferric ion complexes and take a significantly longer time to bleach.

In general, bleaching properties that are not polluting or corrosive to equipment are associated with weak bleaching blades, and therefore bleaching agents with weak bleaching blades, especially bleaching solutions or bleach-fixing solutions using ferric ion complexes or persulfates. It is desired to increase the bleaching capacity of.

(Problems to be Solved by the Invention) The present inventors found that among the many ferric complex salts of aminopolycarboxylic acids, when a bleach solution containing a ferric complex salt of l,3-diaminoprohane tetraacetic acid was used, halogenation occurred. It has been found that silver photographic materials can be rapidly desilvered. However, when processing with the above-mentioned bleaching solution, there has been a problem in that significant staining occurs and photographic properties are significantly impaired.

Therefore, a second object of the present invention is to provide a processing method for rapidly desilvering silver halide color photographic materials.

A second object of the present invention is to provide a desilvering method that hardly causes staining and does not adversely affect photographic properties.
