Abstract
A color diffusion transfer film unit, containing a light-sensitive sheet, a transparent cover sheet provided and an alkaline processing composition-containing material, in which a silver halide emulsion contained in the light-sensitive sheet is a negative type silver halide emulsion, and in which a total coating amount of the silver halide is 0.9 g/m2 or below in terms of silver and from 5 to 10 times greater by number of moles than a total coating amount of a nondiffusing reducing agent contained in color-mixing prevention layers; and an image-forming method using the color diffusion transfer film unit.
Claims6
A color diffusion transfer film unit, comprising a light-sensitive sheet provided, on a first transparent support, with an image-receiving layer, a white reflecting layer, a light-shielding layer, at least three silver halide emulsion layers different in sensitivity for colors, and at least two color-mixing prevention layers containing a nondiffusing reducing agent, each of which is interposed between two layers among the three silver halide emulsion layers;
- a transparent cover sheet provided, on a second transparent support, with a neutralizing layer and a neutralizing timing layer;
- and an alkaline processing composition-containing material to be developed between the light-sensitive sheet and the transparent cover sheet:
- wherein the silver halide emulsion contained in the light-sensitive sheet is a negative type silver halide emulsion;
- and
- wherein a total coating amount of the silver halide is 0.9 g/m2 or below in terms of silver and from 5 to 10 times greater by number of moles than a total coating amount of the nondiffusing reducing agent contained in the color-mixing prevention layers.
