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 5 to 20 mu m, and which expand to 20 to 120 mu m 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 105 DEG C, the high softening point microspheres having softening point greater than 110 DEG C, and the ratio of the low softening point microspheres to the high softening point microspheres being from 9:1 to 1:6. |
