Abstract
Abstract A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer containing at least one cyan coupler represented by the following general formula (I) or (II): <CHEM> wherein Za and Zb each represents <CHEM> or -N=; Zc represents <CHEM> -N= or - @=; 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 of an aromatic primary amine color developing agent; R1 represents a hydrogen atom or a substituent; or R1 or X may form a polymer including a dimer or more. The silver halide color photographic material containing the novel cyan coupler is excellent in color reproducibility and image preservability.
