Abstract

A temporary substrate is lightly coated with graphite and rubbed with a cotton cloth to remove any excess. A dispersion of resin, carbon black, and liquid vehicle is applied to the substrate, solidified by evaporation of the vehicle, and stripped from the substrate. This forms a resistive layer of a thermal ribbon which has graphite embedded in the outer layer. The graphite reduces current requirements, and, since it is embedded, free graphite cannot build-up on the printhead or transfer to the ink layer.
