ABSTRACT:
A silver halide color photographic material comprising a support having thereon one or more layers having a surface pH of 5.0 to 6.5, including at least one silver halide emulsion layer containing a gold-sensitized silver halide emulsion having a silver chloride content of at least 90 mol % and a coupler represented by formula (I): ##STR1## wherein R.sub.1 represents an aryl group or a tertiary alkyl group; R.sub.2 represents fluorine, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, a dialkylamino group, an alkylthio group or an arylthio group; R.sub.3 is a group which is substituted for a hydrogen atom on the benzene ring; X represents hydrogen or a group capable of being cleaved upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; and l is 0 or an integer from 1 to 4.
The silver halide color photographic material is excellent in color reproducibility and has high sensitivity and a good rapid processing aptitude, and is particularly suitable for a color printing material.
