Process for treating a light-sensitive silver halide color photographic material which comprises removing, after color development of the imagewise exposed light-sensitive silver halide color photographic material, the image silver with a bath containing hydrogen peroxide or a hydrogen peroxide releasing compound in combination with at least one compound selected from the group of lower alkyl aliphatic carboxylic acid, alkylidene diphosphonic acid and an alkali metal salt thereof under the conditions of forming substantially no dye image.

Process for treating light-sensitive silver halide color photographic

In the processing of developed imagewise exposed silver halide photographic material with a solution having fixing ability, the fixing efficiency is improved and environmental pollution prevented by employing a solution containing bromine ions or iodine ions as the fixing agent and incorporating in said solution or in a post-bath solution, a polymer having in its molecular structure pyrrolidone nucleus units and a molecular weight of about 2,000 to 500,000.

Process for the treatment of photographic materials

This invention is directed to a bleach-fix which is stable, excellent in bleach-fix efficiency, applicable to the processing of high-speed, light sensitive silver halide color photographic materials and free from problems of environmental pollution.
