Abstract
A thermocolor ribbon, especially a thermocarbon ribbon has a wax and/or plastic binder which melts at a thermal printer temperature to transfer the melt color layer consisting of that binder and polymer particles containing a coloring agent embedded in that binder. The polymer particles melt at a higher temperature to which the thermal print symbol is subjected, e.g. by radiant heating, to fix the image and distribute the coloring agent of the particles in the entire symbol transferred.
