Abstract: A heat-sensitive transferring recording medium comprises a substrate and a solid coating film form by applying a coating material mainly composed of an emulsion and a coloring agent overlying the substrate.

Abstract: A heat-sensitive transferring recording medium comprises a heat-resistant substrate, a heat-sensitive releasing layer and a heat-sensitive transferring ink layer, and the ink layer mainly comprises 50-80 wt. % polyethylene resin having a melting point or softening point of 60.degree.-150.degree. C., molecular weight of 1,000-100,000, penetration of 20 or less (at 25.degree. C.) (JIS K 2235), and melting viscosity of 100-10,000 cps (at 140.degree. C.), 0-30 wt. % wax having a melting point of 50.degree.-110.degree. C., and 5-45 wt. % coloring agent.A heat-sensitive transferring recording medium comprises a heat-resistant substrate, a heat-sensitive releasing layer melting at 50.degree.-100.degree. C. and a heat-sensitive transferring ink layer.

Abstract: A heat-sensitive transferring recording medium is composed of a substrate, a heat-sensitive releasing layer and a heat-sensitive transferring ink layer laminated in the mentioned order.

Abstract: Thermal printing is effected by pressing a heat generating element of a thermal head to paper intervening a transferring ribbon with a heat-sensitive ink layer and immediately after printing, the transferring ribbon is bend so as to detach rapidly the ribbon from the paper.

Abstract: A heat-sensitive transferring recording medium comprises a substrate and a heat-sensitive transferring ink layer overlying the substrate, the heat-sensitive transferring ink layer comprising a coloring agent and two kinds of waxes having melting point of 70.degree.-90.degree. C., penetration (JIS K 2235) of not higher than 5 at 25.degree. C. and specific gravity of 0.99-1.05, one of the waxes having acid value of 120-160 and saponification value of 140-190 and the other having acid value of 1-20 and saponification value of 70-100.

Abstract: A heat-sensitive transferring recording medium comprises a substrate, a heat-sensitive releasing layer, a coloring agent layer and a heat-sensitive cohesive layer.

Abstract: A heat-sensitive transferring recording medium comprises a heat resistant substrate and a heat-sensitive transferring ink layer overlying the heat sensitive substrate, the heat-sensitive transferring ink essentially consisting of (1) a wax of penetration (JIS K 2235) of not higher than 25 (at 25.degree. C.), (2) a resin component composed of both ethylene-vinyl acetate copolymer and aromatic modified terpene resin, and (3) a coloring agent, and the content of the resin component being 10-30% by weight based on the solid matter in the heat-sensitive transferring ink. An overcoat layer may be formed on the heat-sensitive transferring ink layer.
