A color photographic light-sensitive element is described comprising a support having thereon a silver halide emulsion layer containing therein a 3-anilino-5-pyrazolone magenta color-forming coupler represented by formula (I) ##STR1## wherein X represents a halogen atom or an alkoxy group; Ar represents an aryl group; R.sub.1 represents hydrogen, a halogen atom, an alkyl group, an alkoxy group or an alkylthio group; Y represents a non-metallic atomic group forming a 5-membered or 6-membered ring together with the ##STR2## group, except that Y does not include a carbonyl group; and Z represents hydrogen or a coupling-off group. The magenta color images obtained after color development processing of the color photographic light-sensitive element have an excellent light-fastness, and the formation of yellow stain in the unexposed areas thereof is prevented.
