DIFFUSION TRANSFER PHOTOGRAPHIC PRODUCTS COMPRISING A SUPPORT CARRYING AT LEAST TWO SELECTIVELY SENSITIZED SILVER HALIDE EMULSION LAYERS, EACH HAVING A DYE WHICH IS A SILVER HALIDE DEVELOPING AGENT OF PREDETERMINED COLOR ASSOCIATED THEREWITH, AND A LAYER INTERMEDIATE THE EMULSION LAYERS COMPRISING A DYE IMPERMEABLE COALSCED ESSENCE OF AN AQUEOUS FILM-FROMING POLYMER DISPERSION AND A PROCESSING COMPOSITION PERMEABLE MATERIAL ASSOCIATED THEREWITH AND ADAPTED TO RENDER SAID LAYER PERMEABLE TO SOLUBILIZED DYE IMAGE-FORMING MATERIAL SUBSQUENT TO BEING CONTACTED WITH PROCESSING COMPOSITION.
Abstract:
Integral negative-positive patterns viewable without separation of the negative-positive components. Essential elements of such film units comprise a photosensitive system which after exposure and processing can provide a diffusion transfer image pattern, an image pattern receiving system and a reflection system integrated with the elements of the product so that after exposure and processing, the image pattern can be viewed as a reflection print. The image receiving system of the products of the present invention comprise a transparent support or dimensionally stable layer through which the image pattern can be viewed and the transparent support or layer is characterized in that a distinctive UV light absorption capability is integrated therewith. In the especially preferred products, the transparent layer or support additionally comprises a finely divided pigment dispersed therein which provides an effective anti-light piping capability without impairing to any substantial degree the transparency of the support or layer.
