ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, said photographic light-sensitive material containing at least one cyan color-forming coupler represented by the following general formula (I): ##STR1## wherein l represents 0, 1 or 2; X represents a group capable of being released upon the coupling reaction and having at least 6 carbon atoms; Y represents RCONH--, RNHCO-- or RNHCONH-- wherein R represents a hydrogen atom, a methyl group, an ethyl group or a methyl group substituted with one or more halogen atoms; n represents 1 or 2 and Y may be the same or different when n is 2; and the phenyl group can be substituted with a halogen atom, an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms. The dyes formed from the cyan color-forming couplers have unusually good spectral absorption properties and exceptional fastness to light and heat.
