ABSTRACT:
A silver halide color photographic material enables rapid processing, provides a high quality image and has excellent light fastness under extensive conditions, even under high humidity comprises a support, provided thereon at least three silver halide emulsion layers each containing at least one different coupler for forming a different dye by a coupling reaction with the oxidation product of an aromatic primary amine developing agent and each having a different light sensitivity, and at least one anti-color mixing layer provided between each of the emulsion layers and comprising a light-insensitive layer, wherein at least one of the above silver halide emulsion layers contains silver halide grains having a silver chloride content of 90 mole % or more and a magenta coupler represented by the following formula (I) and at least two of the anti-color mixing layers contain at least one anti-color mixing agent having a molecular weight of 350 or more and at least one high boiling organic solvent having the dielectric constant of 5.0 or more: ##STR1## wherein R.sub.1 represents a hydrogen atom or a substituent; Z.sub.a, Z.sub.b, and Z.sub.c each represent methine, substituted methine, .dbd.N--, or --NH--; Y represents a hydrogen atom or a group capable of splitting off upon a coupling reaction with the oxidation product of a developing agent; provided that a dimer or polymer may be formed via R.sub., Y or Z.sub.a, Z.sub.b or Z.sub.c each of which is a substituted methine.
