  • Patent number: 5346800
    Abstract: An image-receiving element for use in photographic diffusion transfer film units of the type wherein the image-receiving element, which includes an image-receiving layer, is designed to be removed, or "peeled-apart", from a photosensitive element after exposure and development have been carried out. The image-receiving element includes a strip-coat layer comprising a hydrophilic colloid, such as gum arabic, and an aluminum salt which overlies the image-receiving layer and significantly reduces striations and/or haze and facilitates the separation of the image-receiving element from the remainder of the film unit subsequent to diffusion transfer photography.
