Abstract
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide color photographic material comprises i) a nondiffusive coupler represented by the general formula (I) or (II): ##STR1## and ii) an acyl acetamide coupler comprising, as an acyl group, a group represented by the general formula (A) ##STR2## The silver halide color photographic material provides a high color density and exhibits a small fluctuation of photographic performance during preservation thereof and improved color image fastness and color reproducibility.
Claims19
A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide color photographic material comprises i) a nondiffusive coupler represented by the general formula (I) or (II) described below:
- ##STR28## wherein X.sub.1 and X.sub.2 each represents an aliphatic or alicyclic hydrocarbon residue, an aryl group or a heterocyclic group;
- X.sub.3 represents an organic moiety necessary to form a nitrogen-containing heterocyclic group together with >N--;
- Y represents an aryl group or a heterocyclic group;
- and Z represents a group capable of being released upon a reaction with an oxidation product of a developing agent;
- said coupler may be in the form of a dimer, a higher polymer or a bis-compound compound which is formed at X.sub.1, X.sub.2, X.sub.3, Y or Z;
- ii) and an acyl acetamide coupler comprising, as an acyl group, a group represented by the general formula (A) described below:
- ##STR29## wherein R.sub.1 represents a mono-valent group, and Q represents a non-metallic atomic group necessary to form a 3-membered, 4-membered or 5-membered hydrocarbon ring or a heterocyclic ring containing at least one hetero atom selected from N, 0, S and P as a ring-forming member together with C, provided that R.sub.1 is not a hydrogen atom and does not combine with Q to form a ring;
- and said coupler may be in the form of a dimer, a higher polymer or a biscompound.
