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 an overcoat layer which overlies the image-receiving layer for reducing the time period for which the image-receiving element remains tacky after the element has been separated from the photosensitive element and for improving the handling and/or storage of the resulting photograph under high humidity conditions. The overcoat layer comprises colloidal silica particles and binder material.
