Abstract
Abstract A color photographic material and a method of forming a color photographic image which utilizes a 5-pyrazolone magenta coupler shown by the following general formula (I): ##STR1## wherein R represents an acylamino group, an anilino group or a ureido group; R 1 , R 2 and R 3 , which may be the same or different, each represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, an alkoxy group, an aryloxy group, a carboxy group, an aryl group or a heterocyclic group (which groups may be substituted) and R.sub. and R 2 may combine to form a 2-indazolyl group, provided that R 1 , R 2 and R 3 are not hydrogen atoms at the same time; and Ar represents a phenyl group which may be substituted with one or more halogen atoms, alkyl groups, alkoxy groups or cyano groups. These 5-pyrazolone magenta couplers are two-equivalent magenta couplers and particularly suitable for providing silver halide color photographic light-sensitive materials having high sensitivity.
