    • 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.

    • A process for forming color photographic images having improved granularity, sharpness, and gradation by applying, after image exposure, a color reversal process including a step of performing color development in the presence of a competing coupler. The element processed is a multilayer reversal color photographic material comprising a support having coated thereon at least three differently sensitive photographic silver halide emulsion layers, the outermost layer of the color photographic material being blue-sensitive and containing a nondiffusible coupler forming a yellow dye by a coupling reaction with an oxidized primary aromatic amino color developing agent and represented by the following general formula (I) ##STR1## wherein R.sub.1 represents an alkyl group or an aryl group; R.sub.2 represents an aryl group or a heterocyclic group; and Z represents a non-metallic atom or the non-metallic atoms required to form a 4-membered ring, a 5-membered ring, or a 6-membered ring together with the ##STR2## moiety, one of the other two layers being green-sensitive and containing a nondiffusible coupler forming a magenta dye by a coupling reaction with an oxidized primary aromatic amino color developing agent, and the other layer being red-sensitive and containing a nondiffusible coupler forming a cyan dye by a coupling reaction with an oxidized primary aromatic amino color developing agent.
