Abstract
Abstract A silver halide color photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer, wherein the silver halide color photographic light-sensitive material contains a cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein R 1 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group; R 2 , R 3 , R 4 and R 5 , which may be the same or different, each represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted acylamino group, a substituted or unsubstituted sulfonamido group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted arylcarbonyl group, a substituted or unsubstituted carbonyl group or a nitrile group, or R 2 and R 3 or R 4 and R 5 may together represent an alkylidene group, R 2 , R 3 , R 4 and R 5 may combine each other to form a ring, three or more of R 2 , R 3 , R 4 and R 5 are not hydrogen atom at the same time and when two of R 2 , R 3 , R 4 and R 5 are hydrogen atoms at the same time, R 2 , R 3 , R 4 and R 5 combine each other to form a ring or R 2 and R 3 or R 4 and R 5 are hydrogen atoms; X represents a hydrogen atom or a group capable of being released upon an oxidative coupling with a developing agent; and n represents 0 or 1. The cyan dye forming coupler can provide a cyan color image having excellent fastness to light and heat and have good solubility in an organic solvent having a high boiling point.
