    摘要: There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.

    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 the formula: 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.

    摘要: Imageable articles having dye selective interlayers comprising copolymers of styrene and vinylidene chloride are disclosed. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be prevented from diffusing away from an image receiving layer. Additionally, the selective interlayers allow unoxidized leuco dye to be diffused away from an image receiving layer, thereby increasing print stability. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color density in the final image.
