Beschreibung
Zusammenfassung:	A dye-donor element for thermal dye transfer comprising 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 area being approximately equal in size to the dye layer area, wherein the transferable protection layer contains inorganic particles, a polymeric binder and unexpanded synthetic thermoplastic polymeric microspheres, the microspheres having a particle size in the unexpanded condition of from about 5 to about 20 mum, and which expand to about 20 to about 120 mum upon application of heat during transfer of the protection layer to an image-receiving layer to provide a matte surface thereon, the transferable protection layer being less than about 1 mum thick.
