Abstract
A color image, wherein granularity is reduced under conditions allowing any sharpness loss to be kept under control, is obtained by image-wise exposing and developing in an alkaline water solution containing a color developer a silver halide color photographic element comprising a support base and at least a silver halide emulsion layer containing dispersed a non-diffusing hydrophobic coupler which upon reactiong with an oxidized developing agent forms a non-diffusing dye, characterized by the fact that said emulsion contains dispersed therein oil droplets, said droplets containing said non-diffusing coupler dissolved therein, and furthermore polymer particles in a quantity sufficient to obtain controlled smearing of the image-forming dye.
