PURPOSE:To obtain a thermal printing medium by which a film printed image can be formed by thermal transfer on the surface of a polyvinyl chloride resin card or the like or an article coated with a polyvinyl chloride resin, by providing a light-transmitting protective layer formed of a material capable of easily welding to he polyvinyl chloride resin and an ink layer on one side of a base. CONSTITUTION:A thermal printing medium is used as a thermal transfer ribbon for a thermal transfer printer. When forming a printed image on a body to be recorded which is formed of a polyvinyl chloride resin, the printing medium is supplied with heat from a thermal head, whereby resins constituting an ink layer 3 and a light-transmitting protective layer 2 are thermally melted, and the surface of the resin of the body to be recorded is also melted or softened. Therefore, a thermal transfer ink melted is transferred to the surface of the body under the pressure exerted by the thermal head, the ink surface is covered by the protective layer, and the melted or softened materials are solidified through cooling. Accordingly, since the thermal transfer ink and the protective layer are transferred to the surface of the body to be recorded thermally softened, in the manner of being embedded into the surface, the transferred image after solidification is resistant to abrasion. |
