Abstract: 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.

Abstract: This invention is concerned with the use of certain pyridine N-oxides in diffusion transfer products and processes employing dye developers.

Abstract: Improved diffusion transfer photographic products and processes wherein a distinctive image-receiving sheet comprising a plurality of layers one of which comprises a polymeric material providing quaternary nitrogen groups is integrated with an integral negative-position diffusion transfer film unit.
