摘要： Disclosed is a silver halide color photographic material comprising a support having thereon at least one layer containing one or more cyan couplers of formula (I): ##STR1## wherein R.sub.11 represents a branched or cyclic alkyl group, a branched or cyclic alkoxy group, a substituted aryl group, or a substituted aryloxy group; R.sub.21 represents a substituent which may optionally be substituted. R.sub.12 represents an aliphatic group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, an alkylamino group, an anilino group, a heterocyclic-oxy group, or a heterocyclic-amino group; R.sub.22 and R.sub.32 each represents a substituent; r.sub.2 represents an integer of from 0 to 4; provided that when r.sub.2 is a plural number, the plurality of R.sub.32 groups may be the same or different; R.sub.13, R.sub.23 and R.sub.33 each represent a hydrogen atom or a substituent; provided that the total of Taft's substituent constant .sigma.* values of R.sub.13, R.sub.23 and R.sub.33 is 1.5 or more; R.sub.43 represents a substituent. In formulae (I), (II) and (III), X.sub.1, X.sub.2 and X.sub.3 each represents a hydrogen atom, or a group which is capable of splitting off from the formula by a coupling reaction with an oxidation product of an aromatic primary amine color developing agent; and the group of R.sub.11, R.sub.21 or X.sub.1, the group of R.sub.12, R.sub.22, R.sub.32 or X.sub.2, or the group of R.sub.13, R.sub.23, R.sub.33, R.sub.43 or X.sub.3 may be a divalent group to form a dimer or a higher polymer or to bond to a polymer chain to form a homopolymer or a copolymer. The material forms a color image with good color hue and color fastness. It is hardly fogged, and the dyes formed from the couplers hardly associate with each other in the material.
