Abstract: A dye-donor element for thermal dye transfer comprising a support having on one side thereof a dye layer and on the other side a slipping layer comprising a binder containing polyalkylsilsesquioxane particles wherein less than about 8% of the particles have a diameter of >0.8 .mu.m.

Abstract: A dye-receiving element for thermal dye transfer comprising a support having on one side thereof a polymeric dye image-receiving layer and on the other side thereof a backing layer comprising a water-soluble polymeric binder, inorganic particles, and a cationic, polymeric mordant for anionic dyes.

Abstract: A dye-receiving element for thermal dye transfer comprising a support having on one side thereof, in order, a cushion layer of an acrylic polymer, a subbing layer, and a polymeric dye image-receiving layer, wherein said subbing layer is a poly(vinyl acetal) and is present at a coverage of at least 0.17 g/m.sup.2.

Abstract: This invention relates to a dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising an image dye dispersed in a binder, wherein the binder contains hydroxyl groups which have been crosslinked with a titanium alkoxide crosslinking agent and the number of carbon atoms in the alkyl moiety of the alkoxide does not exceed four.

Abstract: A dye-donor element for thermal dye transfer comprises a support, a hydrophilic dye barrier/subbing layer comprising a mixture of polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP) and a dye layer. The PVA is present in the mixture from about 15 to about 35 weight-percent. The dye-barrier/subbing layer provides improved dye transfer densities.

Abstract: A dye-donor element for thermal dye transfer comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye layer also containing at least one particulate polypropylene wax having an average particle size less than about 30 .mu.m and having a melting point above about 125.degree. C. Use of the particulate wax minimizes various printing defects without reducing gloss.

Abstract: Photographic elements, film units, processes and alkaline processing compositions are described wherein certain 4-hydroxyalkyl-substituted 3-pyrazolidinones are employed as electron transfer agents in black-and-white and color image transfer materials. The silver halide electron transfer agents or precursors thereof have the following formula: ##STR1## wherein: n is 1 or 2;R repesents hydrogen or a hydrolyzable moiety;R.sup.1 represents an alkyl or substituted alkyl group of 1 to about 6 carbon atoms, an aryl or substituted aryl group of 6 to about 10 carbon atoms, or an aralkyl group of 6 to about 10 carbon atoms;R.sup.2 and R.sup.3 each independently represents hydrogen, an alkyl or substituted alkyl group of 1 to about 6 carbon atoms, an aryl or substituted aryl group of 6 to about 10 carbon atoms, or an aralkyl group of 6 to about 10 carbon atoms; andR.sup.4 represents hydrogen or one or more alkyl or alkoxy groups having from 1 to about 4 carbon atoms, methylenedioxy groups or ethylenedioxy groups.
