    摘要： Photosensitive elements for color diffusion transfer film units comprising a support layer, at least two selectively-sensitized silver halide layers having image-dye forming materials associated therewith, and a novel interlayer, separating the silver halide layers, comprising a polymeric hydroxamic acid polyvalent metal salt which serves as a barrier to the migration of solubilized image-dye forming material until it is rendered permeable to the image-dye forming material subsequent to contact with a sequestering agent for the polyvalent metal of the salt barrier.

    摘要： Acid can be generated by exposing a mixture of a superacid precursor and a dye to actinic radiation of a first wavelength which does not, in the absence of the dye, cause decomposition of the superacid precursor to form the corresponding superacid, thereby causing absorption of the actinic radiation and decomposition of part of the superacid precursor, with formation of a protonated product derived from the dye, then irradiating the mixture with actinic radiation of a second wavelength, thereby causing decomposition of part of the remaining superacid precursor, with formation of unbuffered superacid. Preferably, following these irradiations, the imaging medium is heated while the superacid is admixed with a secondary acid generator capable of being thermally decomposed to form a second acid, the thermal decomposition of the secondary acid generator being catalyzed by the presence of the superacid. The acid generation process may be used for imaging by bringing the superacid or second acid into contact with an acid-sensitive material which changes color on contact with acid, or the superacid may be used to trigger polymerization, depolymerization or other reactions.

    摘要： Copolymeric mordant materials containing recurring units according to the following formula are disclosed: ##STR1## In such copolymers, each of R.sup.1, R.sup.2 and R.sup.3 can independently be alkyl; substituted-alkyl; cycloalkyl; aryl; aralkyl; alkaryl; or at least two of R.sup.1, R.sup.2 and R.sup.3, together with the quaternary nitrogen atom to which they are bonded, can complete a saturated or unsaturated, substituted or unsubstituted nitrogen-containing heterocyclic ring; X is an anion; R.sup.4 is hydrogen or alkyl (e.g. methyl). The pendent "b" group contain hydrogen-bonding sites for promotion of self-associated aggregation and ring unsaturation for photocyclization and control of physical properties (e.g., water insensitivity) of the image-receiving layer. The copolymeric mordant materials can be utilized as image-receiving layers in photographic products and processes of the diffusion transfer type. The mordants are especially adapted to the production of dye images exhibiting favorable maximum density (D.sub.max) and rates of dye transfer properties.

    摘要： An image-receiving element for use in photographic diffusion transfer film units of the "peel-apart" type is disclosed, comprising a support material; a polymeric acid-reacting layer; a water-permeable, water-absorbing polymeric layer for the gathering of processing moisture and image-degrading salt species; a thin, polymeric latex-deposited, water-impermeable and non-absorbing timing layer which is substantially impermeable to alkali for a predetermined period until the occurrence of a predetermined chemical reaction and conversion of said layer to a condition of permeability to alkali; and an alkali-permeable and dyeable image-receiving layer.
