- the present invention concerns a silver halide color photosensitive material.
- Silver halide color photosensitive materials are generally processed in a color developing step and a desilvering step.
- exposed silver halide is reduced by a color developing agent to produce silver, while the oxidized color developing agent reacts with a coupler to provide a dyed image.
