ABSTRACT:
A thermocarbon ribbon having a foil-type carrier and a color transfer layer or melt color has its adhesion for the the paper substrate increased by an adhesion coating applied to the color transfer layer. The adhesion layer consists of a parafin wax matrix in which a sticky hydrocarbon resin is dispersed in finely divided form so that during printing, when the temperature of the adhesion layer is raised, the paraffin wax melts, dissolves the finely divided hydrocarbon resin and allows the sticky characteristic of the latter to increase adhesion of the color transfer material to the paper.
