ABSTRACT:
A color photographic light-sensitive element comprising a support having thereon a silver halide emulsion layer containing therein a 3-anilino-5-pyrazolone magenta-color-forming coupler represented by the following general formula (I): ##STR1## wherein ##STR2## (an N-substituted acylamino group) is present at the 4- or 5-position of the anilino group; R.sub.1 represents a substituted or unsubstituted alkyl group, an alkenyl group, a cycloalkyl group, a cycloalkyl, a cycloalkenyl group or an aralkyl group; R.sub.2 represents an aliphatic hydrocarbon group, a heterocyclic group or an aryl group; X represents a halogen atom or an alkoxy group; Z represents hydrogen or a coupling-off group; and Ar represents an aryl group.
The 3-anilino-5-pyrazolone magenta-color-forming coupler is useful in preventing the formation of yellow stain due to light irradiation in unexposed areas of a color photographic light-sensitive element after color development processing.
