Abstract
Abstract The present invention provides silver halide color photographic materials having a layer which contains at least one magenta color image-forming oleophilic coupler of the following formulae (I) and/or (II) and at least one of the following formula (III): ##STR1## in which Ar represents a phenyl group which is substituted by at least one substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group and a cyano group; Y represents an acylamino group or an anilino group; and Z 1 represents a group capable of being removed by coupling, ##STR2## in which X represents a hydrogen atom or a substituent; Z 2 represents a hydrogen atom or a group capable of being removed by coupling; W represents a hydrogen atom, an acyl group or an aliphatic or aromatic sulfonyl group; Za and Zb each represent a methine group, a substituted methine group or --N═; and X, Z 2 or the substituted methine of Za or Zb may form a dimer or higher polymer, ##STR3## in which A represents an alkyl group, an aryl group, a heterocyclic group, an acyl group, an alkoxy group, an aryloxy group, a heterocyclic oxy group, an alkylthio group, an arylthio group or an amino group, which may be substituted or unsubstituted; R 1 and R 2 each independently represents a hydrogen atom or a substituted or unsubstituted alkyl group; R 3a and R 3b each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkylthio group or an arylthio group; R 4 represents an alkyl group, an aryl group or a heterocyclic group; and D represents an oxygen atom or a sulfur atom. The use of the combination of the magenta couplers(s) of the formulae (I) and/or (II) and the stain-inhibitory additive(s) of the formula (III) provides photographic light-sensitive materials that are almost free from stains when such materials are preserved for a long period of time after having been exposed, developed and then photographically processed.
