    • A silver halide color photographic material in disclosed which comprises a support having thereon at least one silver halide emulsion layer, wherein the photographic material contains at least one compound represented by general formula (I) and at least one compound represented by general formula (II) in combination:Cp--(TIME).sub.n --X--Dye (I)wherein Cp represents a coupler residue capable of releasing --(TIME).sub.n --X--Dye upon coupling with an oxidation product of an aromatic primary amine developing agent; TIME represents a timing group; n represents 0 or a positive integer; Dye represents a dye residue, and X represents an auxochromic group of said dye; ##STR1## wherein R represents a hydrogen atom or a substituent; Y represents a hydrogen atom or a coupling-off group; Za, Zb and Zc each represents a methine group, a substituted methine group, .dbd.N-- or --NH--; either the Za--Zb bond or the Zb-Zc bond represents a double bond and the other represents a single bond, provided that when Za, Zb or Zc represents a substituted methine group, one of the substituted methine group or R may be a divalent group capable of linking to form a dimer or higher polymer, and provided that Y does not represent --(TIME).sub.n --X--Dye as defined in general formula (I). The photographic material has improved sharpness and color reproducibility.
