Abstract
A silver halide color photographic material is provided that contains at least one pyrazoloazole type coupler represented by formula (I) ##STR1## wherein Za and Zb each represents ##STR2## or .tbd.N--, R.sub.1 and R.sub.2 each represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a heterocyclic group, a cyano group, an alkoxy group, an aryloxy group, a heterocyclic hydroxyl group, an acyloxy group, a carbamoyloxy group, a silyloxy group, a sulfonyloxy group, an acylamino group, an anilino group, a ureido group, an imido group, a sulfamoylamino group, a carbamoylamino group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonamido group, a carbamoyl group, an acyl group, a sulfamoyl group, a sulfonyl group, a sulfinyl group, an alkoxycarbonyl group, and an aryloxycarbonyl group, and X represents a hydrogen atom or a group cleavable in a coupling reaction with an oxidized aromatic primary amine developing agent, and in the case where Za=Zb is a carbon-carbon double bond, the double bond may form part of a condensed aromatic ring, and which pyrazoloazole type coupler may form a dimer or a more higher polymer via R.sub.1, R.sub.2 or X; and at least one of compounds having the following formula (II) ##STR3## wherein R.sub.3 and R.sub.4 each represents a hydrogen atom or a straight or branched alkyl group containing from 1 to 10 carbon atoms, provided that the sum of the numbers of carbon atoms of R.sub.3 and R.sub.4 is from 4 to 11.
