Image-receiving element including a polymer with a mordant group grafted onto the backbone thereof

Abstract From the Canadian patent

Image-receiving elements and photographic diffusion transfer products providing diffusion transfer transparency images are described. The image-receiving elements include a transparent support carrying, in sequence an acid-reacting, reagent; a first polymeric timing layer possessing decreasing alkaline solution permeability with increasing temperature; a second timing layer comprising cellulose acetate; and an alkaline solution-permeable and dyeable polymeric imagereceiving layer comprising a graft polymer having a polymeric backbone and grafted thereto moieties which provide mordant capability. The utilization in the image-receiving elements of the aforedescribed first and second timing …
