    摘要： A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye layer and on the opposite side thereof a slipping layer comprising a lubricating material, and wherein a hydrophilic dye-barrier layer is located between the dye layer and the support, and a subbing layer is located between the dye-barrier layer and the support. The dye-barrier layer prevents wrong-way transfer of dye into the support which provides improved dye transfer densities. The subbing layer improves adhesion between the dye-barrier layer and the support.

    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.
