ABSTRACT:
A silver halide color photographicmaterial capable of providing an excellent rapid processing property and sharpness as well as forming little stain on a background after processing. The silver halide color photographic light-sensitive material comprises a reflection support provided thereon at least one of each of yellow color developing silver halide emulsion layer, magenta color developing silver halide emulsion layer and cyan color developing silver halide emulsion layer, wherein the spectral sensitivity peaks of the emulsion layers reside in 400 to 490 nm, 530 to 570 nm and 660 to 720 nm, respectively; wherein a silver halide emulsion contained in the cyan color developing silver halide emulsion layer comprises silver halide emulsion comprising silver halide selected from silver chloride, silver bromochloride, silver chloroiodide or silver bromochloroiodide each having an average silver chloride content of 90 mol % or more, and at least one thiocyanic acid salt compound and wherein the spectral sensitivity peak of the cyan color developing silver halide emulsion layer is provided by a J-band absorption of a sensitizing dye represented by the following Formula (I): ##STR1## wherein Z.sub.23 and Z.sub.24 each represent a group of atoms necessary to form a heterocyclic nucleus selected from a benzothiazole nucleus, a benzoselenazole nucleus, a naphthothiazole nucleus and a naphthoselenazole nucleus, each of which may have at least one substituent selected from a halogen atom, an alkyl group, an alkoxy group, an aryl group, and a hydroxyl group, provided that two of the substituents may be combined with each other to form a ring; R.sub.25 represents a hydrogen atom, an alkyl group or an aryl group; R.sub.23 and R.sub.24 each represent a substituted or unsubstituted alkyl group; X.sub.21 represents a counter ion; and n.sub.21 is 0 or 1.
