摘要

Mfg. a thermal ink ribbon for thermal transfer printing involves using an aqueous coating dispersion. This holds thermoplastic bonding material, a wax and/or wax-like substance and a fat-soluble colouring material in a finely distributed form. The coating dispersion is applied to the carrier foil of the ink ribbon, the water content is evaporated and the wax and/or wax-like substance melted during heat treatment. The water content is evaporated off by heating to a temp. below the melting point of the wax.
