Abstract

A silver halide color photographic material excellent in color reproducibility, color forming property, color image fastness and processing dependency. The material comprises a yellow color forming silver halide emulsion layer formed on a support, said layer containing at least one yellow color forming coupler represented by general formula (I) dispersed by dissolution in a high boiling organic solvent in a weight ratio of the high boiling organic solvent to the yellow color forming coupler of 0.6 or more: ##STR1## wherein X represents an organic residue necessary for forming a nitrogen-containing heterocycle with a nitrogen atom; Y represents an aromatic group or a heterocyclic group; Z represents a group which is eliminatable by reaction of the coupler represented by general formula (I) with an oxidation product of a developing agent.

Dependent claims

A silver halide color photographic material comprising, on a support, at least one cyan color forming silver halide emulsion layer, at least one magenta color forming silver halide emulsion layer and at least one yellow color forming silver halide emulsion layer, which differ from one another in color sensitivity, wherein a yellow color forming silver halide emulsion layer comprises a water-insoluble polymer and at least one yellow color forming coupler represented by the following formula (I) dispersed by dissolution in a high boiling organic solvent in a weight ratio of the high boiling organic solvent to the yellow color forming coupler of 1.0 to 3.0:

##STR199## wherein X represents an organic residue necessary for forming a nitrogen-containing heterocycle with a nitrogen atom;
Y represents an aromatic group or a heterocyclic group;
Z represents a group which is eliminatable by reaction of the coupler represented by formula (I) with an oxidation product of a developing agent, wherein the weight ratio of water-insoluble polymer to said at least one yellow coupler of formula (I) is 0.02 to 2.0, and wherein said high boiling organic solvent is represented by the following general formula (S-1):
##STR200## wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, each represent an alkyl group, a cycloalkyl group, an aryl group, an alkoxy group, a cycloalkyloxy group or an aryloxy group.
