Thermal-print ribbons and method of making same |
摘要 |
A method of making a thermal-transfer ribbon for thermal printing in which an aqueous dispersion of the thermoplastic binder substance, a fat-soluble dyestuff and a wax or waxlike substance is formed. The dispersion is coated onto a foil or other carrier for the ribbon and water is evaporated. The coating is then subjected to a thermal treatment to melt the wax and dissolve the dyestuff therein prior to thermotransfer to a substrate.
