Abstract
A silver halide color photographic material comprising a support having thereon at least one red-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer and at least one blue-sensitive silver halide emulsion layer, where the red-sensitive halide emulsion layer contains a dispersion of oleophilic fine particles which is obtained by emulsifying or dispersing a solution containing at least one cyan coupler represented by the general formula (I) and at least one water-insoluble and organic solvent-soluble homopolymer or copolymer, the green-sensitive silver halide emulsion layer contains at least one magenta coupler represented the general formula (II) or (III), the blue-sensitive silver halide emulsion layer contains at least one yellow coupler represented by the general formula (IV), and the silver halide color photographic material contains at least one compound represented by the general formula (B): ##STR1## Moieties are defined in the specification. The multilayer silver halide color photographic material of the present invention is good in color forming property, improved in image preservability, and free from adverse changes in color balance, as well as having high sensitivity and exhibiting less change in sensitivity with the lapse of time.
