THERMOFARBBAND SOWIE VERFAHREN ZU DESSEN HERSTELLUNG

摘要

A thermocolor ribbon comprises a plastic support foil, a fusible color layer attached to one side of the plastic support foil and an organic coating layer covering the other side of the plastic support foil. The organic coating layer is composed of a nonfibrous, pressure-stable wax or waxlike substance. A process for making the thermocolor ribbon from a plastic support foil having a fusible color layer thereon comprises application of a solution containing an organic coating material to the side of the foil not having the fusible color layer bonded thereto, followed by solvent evaporation. Alternatively, the side of the support foil bearing the fusible color is brought into intimate contact with opposite side of the foil whereupon the latter is heated for a time sufficient for transport of material from the fusible color layer to the uncoated side of the foil to form the organic coating layer thereon.
