Abstract
In a process for providing a color image which comprises imagewise exposing a multilayered light-sensitive photographic material comprising a support and a light-sensitive silver halide emulsion layer not having a coupler incorporated therein and thereafter developing said exposed photographic material with a coupler-containing color developer, the speed and color density of the image are improved by incorporating into the light-sensitive silver halide emulsion layer or the layer contiguous therewith oil particles of a high boiling solvent such as phthalate, phosphate, amide and alcohol type solvents.
