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.
