Abstract
An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type where the image-receiving element is designed to be removed, or 'peeled-apart' from a photosensitive element following exposure and photographic processing. The present image-receiving element comprises, in sequence, a support, an image-receiving layer and a strip-coat layer which serves to facilitate separation of the image-receiving element from the photosensitive element after photographic processing. The strip-coat layer comprises an anion of poly(acrylic acid), or a salt thereof, complexed with a cationic quaternary salt. In a preferred embodiment, the strip coat layer may include an ethoxylated alcohol.
