Abstract
A silver halide color photographic material is described, comprising a support having thereon at least a light-sensitive silver halide and a coupler represented by the general formula: A-RED-P, wherein A is a coupler residue capable of cleaving RED-P on reacting with an oxidized color developing agent, P is a group capable of releasing RED after cleavage of RED-P from A, and RED is a group capable of undergoing an oxidation reduction reaction with the oxidized color developing agent only after the cleavage of A and P. This material is greatly improved in sharpness and graininess.
