Zusammenfassung:PURPOSE:To eliminate rubbed scummings and to enhance the printing definition, by using a thermal transfer ink consisting of a wax of 25 or less penetration, a specific resin constituent, and a colorant. CONSTITUTION:A thermal transfer ink is mainly composed of a wax of 25 or less penetration (25 deg.C), a resin constituent consisting of ethylene-vinyl acetate copolymer and aromatic modified terpene resin, and a colorant. The resin constituent is contained 10-30wt% in the solid content of the thermal transfer ink. As an over layer, the material such as a resin, a wax, or a mixture of resin and wax is used. The layer 1-10mum thick is usually used, and that 1-5mum thick is preferable.
