Abstract
A silver halide color photographic material that has at least one silver halide emulsion layer on a support, which emulsion layer contains a compound represented by the following general formula (T) and a yellow coupler represented by the following general formula (Y-I): ##STR1## (where R.sub.1 and R.sub.2 are each a hydrogen atom or an alkyl group; R.sub.3 and R.sub.4 are each a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; R.sub.5 and R.sub.6 are each a hydrogen atom, an alkyl group, an aryl group, an acyl group or an alkoxycarbonyl group; X is a divalent group having a carbon atom as a constituent atom of the 6-membered ring; and n is 0, 1 or 2): ##STR2## (where R'.sub.1 is an alkyl group or a cycloalkyl group; R'.sub.2 is an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R'.sub.3 is a group capable of substitution on the benzene ring; n' is 0 or 1; Y' is a monovalent ballast group, and Z' is a hydrogen atom or an atom or group that are capable of being eliminated upon coupling).
