ABSTRACT:
A siliver halide color photographic material, comprising at least one of magenta couplers having the following general formula (I) ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group that can be cleaved by the coupling reaction with the oxidation product of an aromatic primary amine developing agent; Za, Zb and Zc each represents a methine group, a substituted methine, .dbd.N--or --NH--; one of the Za--Zb bond and the Zb--Zc bond is a double bond and the other is a single bond; and Zb-Zc may be fused to an aromatic ring, the coupler may form a dimer or higher polymer via R.sup.1 or X, and when Za, Zb or Zc is a substituted methine, the coupler may form a dimer or higher polymer through the substituted methine, and at least one of compounds having the following general formula (II): ##STR2## wherein M represents a hydrogen atom, an alkali metal atom, a quaternary ammonium group or a group that can be cleaved under an alkaline condition; and R.sub.2 and R.sub.3 that may or may not be the same each represents a hydrogen atom, a substituted or unsubstituted aliphatic hydrocarbon group, or a substituted or unsubstituted aromatic hydrocarbon group, or R.sub.2 and R.sub.3 may form together a ring.
