Abstract (en)

[origin: CA2193023A1] The invention relates to a thermo-transfer ribbon with a customary carrier, with a wax-based layer of a thermo-transfer color formed on one side ofthe carrier and an additional layer located between the carrier and the wax-based layer. This thermo-transfer ribbon distinguishes itself in that the additional layer is a wax-based separation layer A) for the wax-based layer B) of the thermotransfer color wherein the waxes of the wax-based layer have a melting point of approximately 70.degree. C to 110.degree. C, and wherein in both layers A) and B) a waxsoluble polymer is finely dispersed. The advantages of this thermo-transfer ribbon include the fact that there is no need for development of a topcoat of a dual-layer thermo-transfer color, and that satisfactory prints are obtained with the thermo-printing process.
