Abstract

A process for forming a color photographic image comprising processing a silver halide color photographic light-sensitive material in the presence of a magenta coupler represented by the formula (I) ##STR1## wherein R represents an acylamino group, an anilino group or a ureido group; Ar represents a substituted or unsubstituted aryl group; X represents a non-metallic divalent group forming a saturated or unsaturated 5-membered or 6-membered heterocyclic ring together with the nitrogen atom; and Y represents an acyl group or a sulfonyl group. The 2-equivalent magenta coupler represented by the formula (I) is stable to chemicals and has a good solubility to an organic solvent which is employed to incorporate couplers into a photographic light-sensitive material. A photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer containing the 2-equivalent magenta coupler represented by the formula (I) is also disclosed.

Ar represents a substituted or unsubstituted aryl group;
the ##STR10## group forms a heterocyclic group represented by the formula (IV), (V) or (VI) ##STR11## wherein R.sub.2, R.sub.3 and R.sub.4 each represents a hydrogen atom, a halogen atom, a nitro group, a nitroso group, an acylamino group, a sulfonamido group, a urethane group, a diacylamino group, a ureido group, an alkylthio group, an alkylsulfonyl group, an alkoxy group, an alkylcarbonyl group, an alkoxycarbonyl group, a sulfamoyl group, a sulfo group, a hydroxy group, an acyloxycarbonyl group, an arylthio group, an aryloxy group, a carbamoyl group, a cyano group, an anilino group, an arylsulfonyl group, an aryloxycarbonyl group, an alkyl group having from 1 to 35 carbon atoms, an alkenyl group, a cycloalkyl group, an aralkyl group, an aryl group or a heterocyclic group;
or R.sub.2 and R.sub.4 together, or R.sub.3 and R.sub.4 together for a ring;
and Y represents an acyl group or a sulfonyl group.
