Abstract
Abstract A color photographic light-sensitive material capable of being processed at an ultrahigh speed, which comprises at least two light-sensitive layers on at least one side of a support wherein each layer contains a light-sensitive silver halide emulsion and a nondiffusive oil-soluble coupler capable of coupling with an oxidation proudct of an aromatic primary amine color developing agent to produce a dye, said light-sensitive layers having different sensitive wavelength ranges, said silver halide is silver chloride or silver chlorobromide containing at least 90 mol % of silver chloride, and the alkali-consuming amount of said light-sensitive material is not more than 2.6 mmol/m 2 . A process for the formation of color images using the light-sensitive material, which comprises imagewise exposing light-sensitive material, and then subjecting the material to color development for not more than 20 seconds.
