Abstract

Abstract A silver halide color photographic light-sensitive material comprising a reflective support bearing thereon a green light-sensitive silver halide emulsion layer containing a magenta forming coupler of formula (I) wherein R, is a tertiary alkyl group; R 2 is an alkyl group or an aryl group and X is a releasable group other than hydrogen, which is susceptible to displacement by reaction of the compound of formula (I) with the oxidation products of a color developing agent; a blue light-sensitive silver halide emulsion layer containing a yellow-forming coupler of formula (II) wherein X 1 is a halogen, an alkoxy group or an alkyl group; Y, is a group capable of displacement by formation of a dye during a coupling reaction of the compound of formula (II) with the oxidation products of an aromatic primary amine color developing agent; R 4 is a substituent for a benzene ring and n is an integer of 1 or 2 and a red light-sensitive silver halide emulsion layer containing a cyan-forming coupler of formula (III) or (IV) wherein R 5 is an alkyl group having 1 to 4 carbon atoms; R 6 is hydrogen or an alkyl group having 1 to 15 carbon atoms and R 7 is a halogen, an alkyl group, a hydroxy group or an acyloxy group wherein R 8 is an alkyl group, a halogen, a sulfonamido group, a sulfamoyl group, an arylsulfonyl group, or a hydroxy group; R 9 is hydrogen or an alkyl group and R 10 is hydrogen, a halogen, an alkyl group, a sulfamoyl group or a sulfonamido group.
