Abstract
A thermocarbon ribbon is formed by emulsifying two mutually incompatible thermoplastic polymers melting at heat-transfer temperatures of a wax. The emulsion containing a pigment is applied to a ribbon support and the solvent is evaporated. The ribbon has multi-strike capabilities and improved sharpness of transfer to rough paper resulting from the presence in the solid continuous phase of beads or microspheres of a dispersed phase, both phases being formed by the polymers.
