ABSTRACT:
In a reversal color development process including a black and white development and a color development, the sharpness, granularity and multilayer effect of the color photographic images formed are remarkably improved by subjecting silver halide reversal color photographic materials to black and white development in the presence of a DIR compound, i.e., a non-coupler type compound capable of releasing a development inhibitor upon development, processing the color photographic materials in an aqueous solution of a fogging agent, and then subjecting the color photographic materials to color development.
