6504 ABSTRACT OF THE DISCLOSURE 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 image- receiving 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 layers permits the provision of elements which can be effectively processed over a range of processing temperatures and which are adapted to the provision of transparencies which exhibit desired images without the distracting or otherwise objectionable image defects associated with reticulation.
