| titleOfInvention | Silver halide color photographic material |
| abstract | 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): <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) wherein R11 represents a branched or cyclic alkyl group, a branched or cyclic alkoxy group, a substituted aryl group, or a substituted aryloxy group; R21 represents a substituent which may optionally be substituted. R12 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; R22 and R32 each represents a substituent; r2 represents an integer of from 0 to 4; provided that when r2 is a plural number, the plurality of R32 groups may be the same or different; R13, R23 and R33 each represent a hydrogen atom or a substituent; provided that the total of Taft's substituent constant sigma * values of R13, R23 and R33 is 1.5 or more; R43 represents a substituent. In formulae (I), (II) and (III), X1, X2 and X3 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 R11, R21 or X1, the group of R12, R22, R32 or X2, or the group of R13, R23, R33, R43 or X3 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. |
