Abstract

A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer is disclosed, wherein said light- sensitive material contains a DIR coupler represented by formula (I):
wherein A represents a coupler residue; R represents an alkyl group having from 1 to 4 carbon atoms or a pyridyl group; and n represents 1 when A represents a phenol type or naphthol type coupler residue, or n represents 0 when A represents other coupler residues, and said emulsion layer contains chemically sensitized silver halide grains which individually have a distinct layer comprising silver iodobromide containing from 7 to 45 mol% of silver iodide and which individually have an overall silver iodide content of more than 4 mol%. The photographic material is excellent in sensitivity, graininess, sharpness, color reproducibility, and preservative and is less liable to variation in photographic performance properties even when continuously processed under replenishment.
