    摘要: A dye-receiving element for thermal dye transfer process and assemblage comprises a compression layer between a film support and the dye image-receiving layer which has a greater compressibility than either the support or the receiving layer, is coated at a coverage of at least 2.0 g/m.sup.2, and has an elasticity of less than 500% elongation at break. In a preferred embodiment, the compression layer has a compression modulus of less than 350 mega Pascals. Use of the compression layer minimizes image defects while providing good scratch resistance.

    摘要: A dye-donor element for thermal dye transfer comprises a support, a hydrophilic dye-barrier/subbing layer comprising poly(butyl acrylate-co-2-aminoethyl methacrylate-co-2-hydroxyethyl methacrylate), poly(N-isopropylacrylamide-co-2-aminoethyl)-methacrylate-co-(2-hydroxyethyl methacrylate), poly[(2-chloroethyl)acrylamide-co-ethacrylic acid],or gelatin nitrate and a dye layer. The dye-barrier/subbing layer provides improved dye transfer densities.

    摘要: Photographic assemblages and processes are described employing positive-working redox dye-releasers and a processing composition containing a ketal blocked quinone which is soluble therein. After processing, when the pH is lowered, the free quinone is released for reaction with residual electron transfer agent present in the assemblage to prevent it from reacting with the dye releaser, which would otherwise cause further dye release. D.sub.min stability is thereby improved.
