Abstract
Thermal transfer ribbons with large wax or thermoplastic resin particles within the thermal transfer layer provide a profiled surface which resists transfer of the layer to reverse side of the ribbon when wound onto itself and stored. The large particles preferably have an average diameter in the range of 5 to 20 microns and the thermal transfer layers preferably have an average thickness of less than the average diameter of these large particles. Where the large particles have higher softening temperatures in the range of 50° to 150° C., the energy needed to transfer the thermal transfer layer is reduced.
