Abstract
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the light-sensitive silver halide emulsion layer contains at least one monodispersed emulsion having a particle size distribution such that a coefficient of variation with respect to a particle diameter of silver halide grains, S/r (wherein S represents a standard deviation regarding to a particle diameter and r represents an average particle diameter) is not more than about 0.25, and the silver halide color photographic material contains at least one primary compound capable of releasing, upon a reaction with an oxidation product of a developing agent, a secondary compound which is capable of further releasing a development inhibitor upon a reaction with another molecule of an oxidation product of a developing agent. The silver halide color photographic material is excellent in sharpnes, graininess and color reproducibility and has a broad exposure latitude.
