Abstract
Abstract A silver halide color photographic light-sensitive material. A support has thereon at least one silver halide emulsion layer and a non-light-sensitive layer adjacent to the silver halide emulsion layer. The silver halide emulsion layer contains a cyan coupler having Formula (I) and a compound having Formula (II). The non-light-sensitive layer contains a compound having Formula (II) ##STR1## wherein X is a hydrogen atom or a group which can be split off by the coupling reaction with the 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 necessary to cause the cyan coupler having the Formula (I) and the cyan dye formed from the cyan coupler to be nondiffusible ##STR2## 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.
