PURPOSE:To improve the graininess of a color image by incorporating a component capable of being oxidized to give an oxidation product which permits an oxidation-reduction reaction with an oxidant of a color developing main agent, or a compd. capable of releasing a precursor of said component by reaction with the oxidant of the color developing main agent. CONSTITUTION:The emulsion layer is composed of a component capable of being oxidized in a process of color development processing, and the oxidation product of said component contains a component (a useful component) capable of causing an oxidation-reduction reaction with the oxidant of a color developing main agent or the compd. (compd.) capable of releasing a precursor of said component by reaction with said oxidant. Namely, as said oxidant is produced at a short distance from a reaction site by using a compd. which is subjected to the oxidation-reduction reaction with the color developing main agent after the photographic useful component is oxidized, and the color matter is formed by coupling reaction of the coupler, the space between the coloring matter clouds is buried whereby the gradation effect of the color image generates, and the graininess of said image is improved. |
