Abstract
A silver halide color photographic material containing a novel cyan coupler and capable of forming a cyan dye having a high color density and an excellent light fastness. The photographic light-sensitive material contains at least one 1H-imidazo[1,5-a]imidazole cyan coupler represented by the following Formula (I) in at least one layer provided on a support: ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent; R.sup.2 and R.sup.3 each represent a substituent, provided that at least one of R.sup.1, R.sup.2, R.sup.3 and represents an electron attractive group; and X represents a hydrogen atom or a group capable of splitting off upon a reaction with an oxidation product of a color developing agent.
