ABSTRACT:
A color photographic light-sensitive element comprising a support having thereon a silver halide emulsion layer containing therein a 3-anilino-2-pyrazolin-5-one magenta color forming coupler, which prevents yellow staining at the unexposed areas after color development processing, and which particularly prevents an increase in yellow staining due to irradiation of light with the magenta color images obtained using the color photographic element containing the magenta coupler maintaining a clear color even after irradiation of light.
