ABSTRACT:
A method of forming a color image comprising subjecting an imagewise exposed color photoraphic material to color development at a temperature of from 30.degree. C. to 50.degree. C. and for a period of from 5 seconds to 20 seconds by immersing the photographic material into a color developing solution wherein the solution contacts the surface of the photosensitive layer of the photographic material as a jet stream; wherein said color photographic material comprises a support having thereon at least two silver halide photographic emulsion layers, each of said layers comprising an emulsified dispersion of fine oleophilic grains containing at least one non-diffusive oil-soluble coupler capable of forming a dye by coupling with the oxidation product of an aromatic primary amine color developing agent and at least one high boiling point organic solvent, wherein silver halide grains in all of silver halide photographic emulsion layers on the support comprise at least 95 mol % silver chloride, and the ratio of the silver halide mean grain size calculated for each photographic emulsion layer on the support to that calculated for any other photographic emulsion layer is from 0.77/1 to 1.3/1, and wherein the color photographic material has an alkali-swelled film pH value of at least 9.0.
