ABSTRACT:
A silver halide color photographic material comprising a photographic silver halide emulsion containing a yellow dye-forming coupler represented by the following general formula (I) or (II): ##STR1## wherein R.sub.1 represents an alkyl group or an aryl group; R.sub.2 represents a chlorine atom or a lower alkoxy group having 1 to 4 carbon atoms; R.sub.3 and R.sub.4, which may be the same or different, each represents an alkyl group having 1 to 22 carbon atom, a phenoxyalkyl group having 7 to 32 carbon atoms, a monocyclic aralkyl group or a phenyl group, a phenyl group which is substituted with an alkoxy group, an alkyl group, an acyl group, or an alkoxycarbonyl group; and X is selected from the group consisting of groups represented by the following general formulae (III) to (V): ##STR2## wherein Z.sub.1 represents the non-metallic atoms necessary to form together with the ##STR3## moiety a 5-membered ring or a 6-membered ring, ##STR4## wherein Z.sub.2 represents the non-metallic atoms necessary to form together with the ##STR5## moiety an unsaturated 5-membered ring or an unsaturated 6-membered ring, or ##STR6## wherein Z.sub.3 represents the non-metallic atoms necessary to form together with ##STR7## an imidazole ring, a triazole ring or a tetrazole ring.
