Abstract
Abstract A color photographic light-sensitive material is described, said material comprising a support having coated thereon at least one silver halide emulsion layer containing a 5-pyrazolone magenta coupler represented by formula (I) ##EQU1## wherein R represents an acylamino group, an anilino group or a ureido group; Ar 1 represents a phenyl group which may be substituted with one or more halogen groups, alkyl groups, or alkoxy groups; Ar 2 represents a phenyl group or a naphthyl group, each of which may be substituted with one or more halogen groups, hydroxy groups, carboxy groups, cyano groups, alkyl groups, acylamino groups, carbamoyl groups, ureido groups, sulfonamido groups, diacylamino groups, sulfamoyl groups, alkoxycarbonyl groups, phenyl groups, arysulfonyl groups or alkoxy groups; X represents oxygen, sulfur, or a methylene group; and Y represents a straight chain or branched chain alkylene group having from 1 to 6 carbon atoms, or an alkylene group containing an ether bond.
