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 microspheres comprising a mixture of low softening point microspheres and high softening point microspheres, the low softening point microspheres having a softening point less than about 105° C., the high softening point microspheres having softening point greater than about 110° C., and the ratio of the low softening point microspheres to the high softening point microspheres being from about 9:1 to about 1:6.
