Abstract
A silver halide color photographic material comprising a support having thereon a cyan coupler-containing layer, a magenta coupler-containing layer and a yellow coupler-containing layer, wherein the cyan coupler-containing layer contains a dispersion of oleophilic fine particles which is obtained by emulsifying or dispersing a solution containing (a) at least one cyan coupler represented by the general formula (I) and/or (II) described below, (b) at least one compound represented by the general formula (III) described below and (c) at least one water-insoluble and organic solvent-soluble homopolymer or copolymer, ##STR1## wherein R.sub.1, R.sub.2, and R.sub.4 each represents a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group or a substituted or unsubstituted heterocyclic group, R.sub.3, R.sub.5 and R.sub.6 each represents a hydrogen atom, a halogen atom, an aliphatic group, an aromatic group or an acylamino group, and R.sub.3 may represent a non-metallic atomic group necessary to form a nitrogen-containing 5-membered or 6-membered ring together with R.sub.2, Y.sub.1 and Y.sub.2 each represents a hydrogen atom or a group capable of being released upon a coupling reaction with an oxidation product of a developing agent, and n represents 0 or 1, ##STR2## wherein R.sub.7 R.sub.8, R.sub.9, R.sub.10 and R.sub.11, which may be the same or different, each represents a hydrogen atom, a halogen atom, a nitro group, a hydroxy group, an alkyl group, an alkenyl group, an aryl group, an alkoxy group, an acyloxy group, an aryloxy group, an alkylthio group, an arylthio group, a mono- or di-alkylamino group, an acylamino group or a 5-membered or 6-membered heterocyclic group containing an oxygen atom or a nitrogen atom, and R.sub.10 and R.sub.11 may combine with each other to form a 5-membered or 6-membered aromatic ring. The silver halide color photographic material exhibits excellent stability of coating solution therefor and provides cyan color image having improved fastness both to heat, to humidity and heat and to light.
