Abstract
A description is given of a thermo-transfer ribbon having a customary carrier, with a wax-bonded layer of a thermo-transfer color formed on one side of the carrier, and a resin-bonded separation layer located between carrier and wax-bonded layer, characterized in that at least the resin-bonded separation layer A) contains a wax-soluble polymer and the wax-bonded layer B) of the thermo-transfer color contains less than approximately 8% by weight, specifically 0 to approximately 5% by weight, of wax-soluble polymer, whereby the waxes of the wax-bonded layer B) are narrowly cut waxes with melting- and coagulation points positioned in close proximity to each other. The benefits of said thermo-transfer color consist in that there occur no differences in the quality of the print, either with 'cold' or 'hot' print, and specifically also on uncoated paper with high degree of roughness.
