ABSTRACT:
A silver halide color photographic material comprising a support having thereon at least one silver halide red-sensitive emulsion layer containing at least one cyan coupler represented by formula (I) or (II) ##STR1## wherein Za represents ##STR2## Zb represents ##STR3## Zc represents ##STR4## Y represents a hydrogen atom or a blocking group; X represents a hydrogen atom or a group which releases upon a reaction with an oxidation product or an aromatic primary amine color developing agent; R.sub.11 represents a group which is substantially not released upon reaction with an oxidation product of an aromatic primary amine color developing agent; R.sub.12 represents a hydrogen atom or a substitutent; or R.sub.11, or R.sub.12 or X may form a dimer, oligomer or polymer.
The silver halide color photographic material containing the novel cyan coupler is excellent in color reproducibility and image preservability.
