ABSTRACT:
A silver halide color photographic light-sensitive material has red-, green-, and blue-sensitive silver halide emulsion layers, and the red-sensitive emulsion layer contains a cyan coupler and a yellow coupler with a relative coupling rate of 0.7 to 3.0 with respect to the cyan coupler. In addition, at least one layer may contain a specific DIR compound, the average silver iodide content of a silver halide emulsion contained in the red-sensitive silver halide emulsion may be higher than that of a silver halide emulsion contained in the green-sensitive silver halide emulsion layer, or at least one layer may contain a monodisperse silver halide grain emulsion with a grain diameter/grain thickness ratio of 2 to 8.
