IMAGE-RECEIVING ELEMENT FOR DIFFUSION TRANSFER PHOTOGRAPHIC AND PHOTOTHERMOGRAPHIC FILM PRODUCTS

摘要

An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or "peeled-apart" from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50 % by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15 % by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5 % by weight of monomer units, the same or different, represented by formula (I), wherein R1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from -NH- or -O-; and R2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.
