Electrothermal Printing Ribbon

An improved ribbon for use in electrothermal printing is described. The ribbon comprises a resistive layer in which the physical strength of the ribbon is increased by the addition of a polyester resin PE200 and the use of a plasticizer dibutyl phthalate.

When these materials are added to a polycarbonate resin such as M-50, the percent elongation is significantly improved. In addition, these additives permit printing without "burn through" of the ribbon.

The formulation comprises polycarbonate (N28%), polyester PE200 (N28%) and dibutyl phthalate (N14%). The materials are coated from solution onto a suitable substrate such as polyethylene from which the ribbon can be subsequently easily delaminated.
