Abstract:
A silver halide color photographic material comprising a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains a coupler represented by formula (1) shown below and a non-color forming colorless carboxylic acid compound having a diffusion-resistant group or a salt thereof: ##STR1## wherein R.sup.1 and R.sup.2 each represents an alkyl group or an aryl group; R.sup.3, and R.sup.4 and R.sup.5 each represents a hydrogen atom, an alkyl group or an aryl group; Z represents a non-metallic atomic group necessary to form a saturated ring; R.sup.6 represents a substituent; X represents a heterocyclic group, a substituted amino group or an aryl group and Y represents a hydrogen atom or a group capable of being released upon color development.The silver halide color photographic material has an excellent color forming property to provide a color image of high maximum color density and good color reproducibility.
