Abstract
Disclosed is a silver halide color photosensitive material having on a support at least a cyan color-generating silver halide emulsion layer in which oleophilic fine particles containing both a pyrroloazole type cyan coupler and a phenol or amide type high boiling organic solvent are dispersed, thereby ensuring excellent cyan-color generation performance, desirable spectral sensitivity characteristics and satisfactory color reproduction and making it feasible to reduce the change of the generated color from pure to muddy upon storage under a high temperature-high humidity condition.
