Abstract

The present invention provides a silver halide color photographic photosensitive material having superior image sharpness and film strength. Disclosed is a silver halide color photographic photosensitive material in which a yellow-developing photosensitive silver halide emulsion layer on a support contains at least one dye-forming coupler represented by the following general formula (Y-1), and at least one layer of the non-photosensitive hydrophilic colloid layers on the support contains a dispersion of solid particles of a dye represented by the following general formula [I]. In the general formula (Y-1), Y represents a nitrogen-containing heterocycle; Z represents a substituted aryl group; X represents a hydrogen atom, or a group that leaves by the reaction with an oxidized form of a developing solution. In the general formula [I], D represents a residue of a compound having a chromophoric group; X represents a dissociative hydrogen atom or a group having a dissociative hydrogen atom. General formula (I) D[Parenopenst]X)y
