A silver halide color photographic material is disclosed, comprising a support having provided thereon at least one silver halide emulsion layer containing a cyan-dye-forming coupler represented by formula (I)
wherein Y represents an atomic group forming an at least 7-membered nitrogen-containing heterocyclic ring containing at least one -NHCO- group; Z represents a hydrogen atom or a group releasable upon coupling with an oxidation product of a color developing agent; R represents an aliphatic group, an aromatic group, a heterocyclic group, or a substituted amino group, or any of R, Z and Y form a dimer or higher polymer.
The material forms a dye image excellent in fastness and color reproducibility, and free from white background stains.
