ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, the color photographic light-sensitive material containing a coupler having a group represented by the general formula (I) ##STR1## wherein W represents ##STR2## represents an organic residue necessary for forming a 5-membered or 6-membered nitrogen-containing heterocyclic ring or a condensed ring thereof together with W; Y represents an organic residue connecting Z and X and containing at least one carbon atom which is bonded to Z; Z represents an oxygen atom or a sulfur atom; and n represents an integer of 1 to 2; at the coupling position of the coupler and a method of forming a color image using the silver halide color photographic light-sensitive material. The silver halide color photographic light-sensitive material containing the two-equivalent coupler having a group capable of being released upon a coupling reaction represented by the general formula (I) has a high dye forming rate even when it is processed in a color developing solution which does not contain an organic solvent such as benzyl alcohol.
