Definitions
- the photosensitive element comprises a transparent support coated with an image-receiving layer, an opaque reflecting layer and at least one, and preferably three, silver halide emulsion layers having associated therewith a dye image-providing material, preferably a dye developer.
- an opaque process sheet containing an alkaline processing composition preferably imbided in the sheet in liquid form, is laminated to the photosensitive element as it is withdrawn from the camera.
- the opaque process sheet may contain the processing composition in dry form, e.g., a layer of an alkali source such as sodium carbonate overcoated with pressure-sensitive microcapsoles of water.
- the processing composition develops the exposed silver halide emulsion layers and dye images are formed as a function of development which diifuse to the image-receiving layer to provide a positive, right-reading image which is viewed through the transparent support on the opaque reflecting layer background.
- Developing agents may be present in the processing composition or incorporated in the process sheet or photosensitive element.

Defensive Publication applications have not been examined as to the merits of alleged invention. The Patent Ofllce makel no assertion as to the novelty of the disclosed subject matter.
PUBLISHED DECEMBER 1, 1970 T881,010 PHOTOGRAPHIC FILM UNIT FOR DIFFUSION TRANSFER PROCESSING Harold E. Cole, 8 Cottonwood Lane, Pittsford, N.Y. 14534 Filed May 25, 1970, Ser. No. 40,438 Int. Cl. G03c 1/48 U.S. Cl. 96--76 No Drawing. 16 Pages Specification Color diifusion transfer photosensitive elements and film units are disclosed which are adapted for one-step processing. The photosensitive element comprises a transparent support coated with an image-receiving layer, an opaque reflecting layer and at least one, and preferably three, silver halide emulsion layers having associated therewith a dye image-providing material, preferably a dye developer. After exposure of the photosensitive element, an opaque process sheet containing an alkaline processing composition, preferably imbided in the sheet in liquid form, is laminated to the photosensitive element as it is withdrawn from the camera. Alternately, the opaque process sheet may contain the processing composition in dry form, e.g., a layer of an alkali source such as sodium carbonate overcoated with pressure-sensitive microcapsoles of water. The processing composition develops the exposed silver halide emulsion layers and dye images are formed as a function of development which diifuse to the image-receiving layer to provide a positive, right-reading image which is viewed through the transparent support on the opaque reflecting layer background. Developing agents may be present in the processing composition or incorporated in the process sheet or photosensitive element.
