Abstract
Abstract A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains at least one water-insoluble and organic solvent soluble homopolymer or copolymer and at least one yellow coupler of the formula: ##STR1## wherein R 1 represents a tertiary alkyl group or an aryl group; R 2 represents a hydrogen atom, a halogen atom or an alkoxy group; R 3 represents an alkyl group or an aryl group; and X represents a group capable of being released upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent. The silver halide color photographic material has high sensitivity and excellent sharpness, color reproducibility and preservability, before and after processing, as is free from sweating.
