Abstract
A diffusion transfer film unit, containing a light-sensitive sheet, a transparent cover sheet, and a light-shielding alkaline processing composition, in which an adhesive layer and a peeling-agent layer are arranged so that they are adjacent to each other, the adhesive layer and the peeling-agent layer are disposed at a position closer to a light-exposure position than an image-receiving layer in the light-sensitive sheet or at any position in the transparent cover sheet, and the adhesive layer is disposed on the side closer to the image-receiving layer than the peeling-agent layer.
Claims12
A diffusion transfer film unit, comprising:
- (i) a light-sensitive sheet provided, on a transparent support, with an image-receiving layer, a white reflecting layer, a light-shielding layer and at least one silver halide emulsion layer combined with at least one dye-image-forming substance in this order, on the side of transparent cover sheet described below;
- (ii) a transparent cover sheet provided, on another support, with a neutralizing layer and a neutralizing timing layer in this order on the light-sensitive sheet side;
- and
- (iii) a light-shielding alkaline processing composition to be developed between the light-sensitive sheet and the transparent cover sheet;
- in which (i) the light-sensitive sheet, (ii) the transparent cover sheet and (iii) the light-shielding alkaline processing composition are arranged such that the diffusion transfer film unit is exposed to light through the transparent cover sheet;
- wherein an adhesive layer and a peeling-agent layer are arranged so that they are adjacent to each other, the adhesive layer and the peeling-agent layer are disposed at a position closer to the light-exposure position than the image-receiving layer in the light-sensitive sheet or at any position in the transparent cover sheet, and the adhesive layer is disposed on the side closer to the image-receiving layer than the peeling-agent layer.

- (ii) a transparent cover sheet provided, on a lamination-type transparent support having a constitution in which an adhesive layer and a peeling-agent layer are sandwiched between two supports, with a neutralizing layer and a neutralizing timing layer in this order on the light-sensitive sheet side;
- and
- (iii) a light-shielding alkaline processing composition to be developed between the light-sensitive sheet and the transparent cover sheet;
- in which (i) the light-sensitive sheet, (ii) the transparent cover sheet and (iii) the light-shielding alkaline processing composition are arranged such that the diffusion transfer film unit is exposed to light through the transparent cover sheet.
