Abstract: In a color diffusion transfer photographic element containing at least one dye-releasing redox compound-containing layer associated with a silver halide photographic emulsion and capable of releasing a diffusible dye as a result of a redox reaction with the oxidation product of a developing agent produced by the development of silver halide with an alkaline processing solution, and at least one layer containing an antistain agent, the improvement which comprises said dye-releasing redox compound-containing layer associated with said silver halide photographic emulsion being spaced from the adjacent interlayer containing said antistain agent by a spacer layer essentially containing a hydrophilic colloid or by a silver halide emulsion layer having substantially the same spectral sensitivity as that of the associated silver halide emulsion.

Abstract: A method is disclosed of photographically processing a negative-working imagewise exposed silver halide photographic element to produce a reversal dye image comprising (a) developing the imagewise exposed silver halide with an electron transfer agent to produce oxidized electron transfer agent which reacts with a competing oxidizable substance and (b) developing silver halide remaining with the electron transfer agent in the presence of a dye image providing compound capable, after the competing oxidizable substance has been depleted, of reacting with the oxidized electron transfer agent to produce a reversal dye image. Image transfer film units are disclosed useful in the practice of this method. Such film units include those containing in addition to the competing oxidizable substance and initially immobile dye image providing compound a layer containing additional silver halide and a scavenger separating the additional silver halide from the immobile dye image providing compound.

Abstract: A photographic element comprising a support, a layer containing an image dye ligand or dye ligand forming material and a layer containing a dye mordant, wherein the mordant layer has associated therewith:(1) a polymer containing groups which form coordination complexes with metal ions; and(2) a source of metal ions.The polymer holds the metal ions in the vicinity of the dye mordant so that the metal ions can metallize the dye or dye forming material at the image receiving layer. These complexes, elements, and receiving elements are particularly useful in diffusion transfer processes. Novel polymers are also described.

Abstract: Photographic elements, film units and processes are described having bifunctional benzisoxazolones of the formula: ##STR1## wherein: R is alkyl or aryl;DEV is a silver halide developing agent;Ball is at least one organic ballasting radical of such molecular size and configuration as to render the compound nondiffusible in the photograhic element during development in an alkaline processing composition; andn is a positive integer of 1 to 4.The compounds are employed in negative-working, color image transfer elements and release the developer upon processing. The remainder of the compound functions to scavenge oxidized developer. The compounds can be located in an emulsion layer or in a dye image-providing material layer, and in a ballasted form can be located in an interlayer.

Abstract: Photographic elements, film units and processes are described wherein N-alkyl- or N-aryl-benzisoxazolones are used to scavenge oxidized electron transfer agents in negative-working, color image transfer elements. The scavenger precursor compounds can be located in an emulsion layer or in a dye image-providing material layer, and in a ballasted form can be located in an interlayer.

Abstract: A cover sheet for an integral imaging receiver element comprises a support, a neutralizing layer, at least one timing layer and an alkali permeable hydrophilic layer. The cover sheet may also contain a second alkali permeable layer coated over the alkali permeable hydrophilic layer to promote adhesion of the cover sheet to the other components of the film unit. The photographic film units containing the cover sheets are substantially free from dark spot imperfections and are resistant to delamination of the unit.
