ABSTRACT:
A silver halide color photographic photosensitive material comprises a support, having thereon at least one silver halide emulsion layer, wherein a coupler represented by formula (I) shown below is included in at least one layer of the photosensitive material, and a coupler represented by formula (M) shown below is included in at least one layer of the photosensitive material: ##STR1## wherein R.sub.1 represents an aryl group having substituents the sum of whose Hammett's rule substituent .sigma. constants is at least 0.2, and R.sub.2 represents an aryl group having substituents the sum of whose Hammett's rule substituent .sigma. constants is at least 0.75; ##STR2## wherein R.sub.1 represents a hydrogen atom or a substituent group; Z represents a group of nonmetal atoms which is required to form either (1) a five-membered azole ring which has two or three nitrogen atoms, and which may have substituent groups (including condensed rings), or (2) an unsubstituted five-membered azole ring which has four nitrogen atoms; and X represents a hydrogen atom or a group which can be eliminated at the time of a coupling reaction with an oxidation product of a developing agent.
