Description

ABSTRACT:
The present invention relates to a silver halide color photographic photosensitive material comprising a support having thereon at least one silver halide emulsion layer, wherein a yellow dye forming coupler which is represented by formula (1) indicated below and/or a yellow dye forming coupler which can be represented by formula (2) indicated below are included in said silver halide emulsion layer, and the size distribution of the silver halide grains in said silver halide emulsion layer is mono-disperse: ##STR1## wherein X.sub.1 and X.sub.2 each represent an alkyl gorup, an aryl group or a heterocyclic group, X.sub.3 represents an organic residual group which, together with >N--, forms a nitrogen containing heterocyclic group, Y represent an aryl group or a heterocyclic group, and Z represents a group which is released when the coupler represented by formulae (1) and (2) reacts with the oxidized form of the developing agent.
