Farbstoffgebendes Element für thermische Farbstoffübertragung mit übertragbarer Schutzschicht

摘要

A dye-donor element for thermal dye transfer comprises a support having thereon at least one dye layer area comprising an image dye in a binder and another area comprising a transferable protection layer, the transferable protection layer being approximately equal in size to the dye layer area. The transferable protection layer comprises either (a) poly(vinyl formal), poly(vinyl benzal) or poly(vinyl acetal) containing at least 5 mole % hydroxyl and a crosslinking agent, or (b) a phenoxy resin and a crosslinking agent. Also claimed are: (i) process of forming a protection layer on top of a thermal dye transfer image; and (ii) a thermal dye transfer assembly.
