A thermal printing ribbon is made from an aqueous dispersion of a thermal plastic binder and particles of a wax component, fat-soluble dyestuff and a pigment so that these particles are found side by side in the interstices of a skeleton or matrix formed by a thermoplastic. The thermal printing ribbon has a multistrike capacity.

Thermal-print ribbon with thermoplastic matrix and method of making same

An aqueous ink eradicator solution for inks utilizing triaryl methane dyestuff and containing a reducing sulfur compound. the ink contains 20 to 50% by weight of sugar and/or a solid sugar alcohol and the reducing sulfur compound in an amount of 0.5 to 5% by weight.

Ink eradicator for inks containing triaryl methane dyestuffs

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.
