Abstract
Abstract A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer containing a cyan coupler of Formula [I] and a compound of Formula [II] and a non-light-sensitive layer adjacent to said silver halide emulsion layer containing a compound of Formula [II]; Formula [I] wherein X is a hydrogen atom or a group which can be split off by a coupling reaction with an oxidized product of an aromatic primary amine color developing agent; R 1 is an aryl group or a heterocyclic group; and R 2 is a ballasting group such that said cyan coupler of Formula [I] and the cyan dye formed from said cyan coupler are nondiffusible; Formula [II] wherein R 3 and R 4 each is an alkyl group, an alkenyl group, or a cycloalkyl group each having from 3 to 20 carbon atoms, or an aryl group having from 6 to 20 carbon atoms.
