ABSTRACT:
A silver halide color photographic material having a support and at least one hydrophilic colloid layer provided thereon, the hydrophilic colloid layer containing a dispersion obtained by dissolving a diffusion resistant oil-soluble cyan coupler which forms a substantially nondiffusible dye by coupling with an oxidation product of an aromatic primary amine developing agent and a hydrophobic polymer latex formed in an aqueous medium in each other, in which the polymer latex has a recurring unit represented by the following general formula (I), the cyan coupler is represented by the following general formula (II) or (III), and the disperison is formed through a water-in-oil emulsion at least once when the hydrophobic polymer latex formed in the aqueous medium is mixed with a solution of the cyan coupler in a coupler solvent: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, Y.sub.1, Y.sub.2 and n are as defined above.
