ABSTRACT:
A silver halide color photographic material comprising a support having thereon a yellow coupler-containing silver halide emulsion layer, a magenta coupler-containing silver halide emulsion layer and a cyan coupler-containing silver halide emulsion layer, wherein each silver halide emulsion layer contains silver halide grains having a silver chloride content of not lower than 90 mol %, a yellow coupler in said yellow coupler-containing silver halide emulsion layer is coated in an amount of at least 1.1 mmol/m.sup.2, oil/coupler ratio by weight in the yellow coupler-containing silver halide emulsion layer is 0.32 or less and the magenta coupler-containing layer contains at least one magenta coupler represented by the following general formula (I): ##STR1## wherein R.sup.1 and R.sup.2 represent each a hydrogen atom or a substituent group; X represents a hydrogen atom or group which is eliminated by a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Z represents a nitrogen atom or a carbon atom and when Z represents carbon atom, a substituent group may be bonded to said carbon atom; and a dimer or a higher polymer may be formed through R.sup.1, R.sup.2 or X, or when Z is carbon atom, a dimer or a higher polymer may be formed through said carbon atom.
