A process for forming a color photographic image is described comprising processing a silver halide color phototgraphic light-sensitive material in the presence of a 5-pyrazolone magenta coupler represented by the formula (I) ##STR1## wherein R represents an acylamino group, an anilino group or a ureido group; R.sub.1 represents a nitro group, a nitroso group, an amino group, an acylamino group, a sulfonamido group, a urethane group, a diacylamino group or a ureido group; Q represents hydrogen, a halogen atom, a substituted or unsubstituted alkyl group, an alkenyl group, a cycloalkyl group, an aralkyl group, an alkoxy group, an aryloxy group, a carboxy group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a thiourethane group, a thioureido group, an acylhydrazino group, an alkylamino group, a dialkylamino group, an anilino group, an alkylthio group, a mercapto group, an arylthio group, an alkylsulfinyl group, an alkylsulfonyl group, an arylsulfinyl group, an arylsulfonyl group, a sulfamoyl group, a sulfo group, a thiocyano group, a hydroxy group, an aminocarbonyloxy group, an acyloxy group, a sulfonyloxy group, an alkylcarbonyl group, an arylcarbonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an aralkyloxycarbonyl group, a cyano group; Ar represents a phenyl group which may be substituted with one or more halogen atoms, alkyl groups, alkoxy groups or cyano groups; m represents an integer; n represents 0, 1 or 2; and m and n must satisfy the following relation, 1.ltoreq.m+n.ltoreq.3. The 2-equivalent magenta coupler represented by the formula (I) is stable to the attack of chemicals and capable of forming a magenta dye in high yield without forming undesired fog or stain.
