Silver halide color photographic material |
摘要 |
A silver halide color photographic material containing at least one coupler compound of the formula (1) in at least one hydrophilic colloid layer which is provided on a support: R1OCOCHXCONR2R3(1) where R1 represents a branched alkyl group including a cyclic alkyl group and a cyclic alkyl-substituted alkyl group, an aryl group or a heterocyclic group; R2 represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; R3 represents an alkyl group, an aryl group or a heterocyclic group; X represents a group which splits off from the coupler compound when the coupler compound is reacted with an oxidation product of an aromatic primary amine developing agent; and R2 and R3 may be bonded to each other to form a ring. The coupler has a high dye-forming rate to give a dye having a high color density and a high color fastness. The material has improved sharpness and color fastness and an elevated sensitivity.
