Abstract
A photographic light-sensitive material for a color diffusion transfer process is described, comprising a support having provided thereon (1) at least two silver halide emulsion layers which are in combination with dye-releasing redox compounds, and (2) an intermediate layer between said silver halide emulsion layers; the intermediate layer comprises a hydrophilic colloid having dispersed therein two or more different kinds of particles, with one or more kinds of said particles containing a scavenger for an oxidized product of a developing agent. The material has an improved processing temperature latitude.
Claims9
A photographic light-sensitive material for a color diffusion transfer process comprising a support having provided thereon (1) at least two silver halide emulsion layers which are in combination with dye-releasing redox compounds capable of releasing diffusible dyes upon redox reaction with an oxidized product of a silver halide developing agent which is formed by processing development with an alkaline processing solution in the presence of a silver halide developing agent, and (2) an intermediate layer between said silver halide emulsion layers which comprises a hydrophilic colloid having dispersed therein particles containing a reducing component capable of reacting with the oxidized product of the developing agent, wherein said particles comprise:
- (a) a mixture consisting of two or more kinds of dispersed particles, each comprising said reducing component as a first component and a second component which is miscible with the first component to constitute dispersed particles, wherein said two or more kinds of dispersed particles differ from each other in that the second component is different among the two or more kinds of dispersed particles, or the proportion of the second component to the first component is different among the two or more kinds of dispersed particles;
- or
- (b) a mixture consisting of dispersed particles substantially solely comprising said reducing component as a first component and one or more kinds of dispersed particles comprising the same reducing component as said first component and a second component which is miscible with said first component to constitute dispersed particles.
