ABSTRACT:
A silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer, wherein at least one of the silver halide emulsion layers contains at least one magenta coupler represented by the general formula (I) described below, at least one organic solvent having a high boiling point which has at least one ##STR1## bond in its molecule, wherein R.sub.13 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkylthio group or an arylthio group, and at least one compound represented by the general formula (II) described below: ##STR2## wherein Za and Zb each represents ##STR3## or .dbd.N--; R.sub.1 and R.sub.2 each represents a hydrogen atom or a substituent; X represents a hydrogen atom or a group capable of being released upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; when the Za-Zb bond is a carbon-carbon double bond, it may form a part of a condensed aromatic; and R.sub.1, R.sub.2 or X may form a polymer including a dimer or a higher polymer, ##STR4## wherein R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each represents and alkyl group having from 1 to 18 carbon atoms; R.sub.7 represents a hydrogen atom or an alkyl group having from 1 to 12 carbon atoms; and n represents an integer of 1 to 3, with the proviso that when n is 2 or 3, two or three groups represented by R.sub.7 may be the same or different, and when n is 1, the group represented by R.sub.7 is the alkyl group defined above.
