Abstract
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 of the 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 thermo-transfer 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 wax-soluble 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.

A thermo-transfer ribbon comprising a carrier material having deposited on one side of said carrier a wax layer B) of a thermo-transfer color and having an additional layer A) arranged between said carrier and said wax layer, said ribbon being characterized in that said additional layer is a resin separation layer A) for said wax layer B) wax, that the wax of said wax layer have a melting point of approximately 70.degree. C. to 110.degree. C., and that in both said layers A) and B) a wax-soluble polymer is finely dispersed.
A thermo-transfer ribbon consisting essentially of a ribbon having deposited on one side a color layer comprised of a coloring agent, a wax having a melting point of approximately 70.degree. C. to 110.degree. C., and a finely dispersed wax-soluble polymer, and a release layer positioned between said color layer and said ribbon, said release layer comprised of a resin and a finely dispersed wax-soluble polymer.
A thermo-transfer ribbon comprised of a carrier having deposited thereon a release layer, said release layer comprised of a resin, 10 to 60 percent by weight of a finely dispersed wax soluble polymer and optionally a colorant, and a color transfer layer deposited on said release layer, said color transfer layer comprised of wax, a colorant, and at least 2 to 20 percent by weight of a finely dispersed wax-soluble polymer.
