  • Patent number: 5196080
    Abstract: A heat transfer sheet comprising a base film and a hot melt ink layer formed on one surface of the base film, said hot melt ink layer comprising one or more components which impart filling to the printed areas of a transferable paper during transferring. Another type of a heat transfer sheet comprising a base film, a hot melt ink layer laminated on one surface of the base film, and a filling layer laminated on the hot melt ink layer, said filling layer comprising one or more components which impart filling to the printed areas of a transferable paper during transferring. According to the heat transfer sheets, high quality printing can be attained even at a high speed without any staining.

  • Patent number: 4916006
    Abstract: A heat-sensitive transfer recording material for use in a heat-sensitive transfer recording means such as a thermal printer is provided. The recording material comprises a heat-sensitive transfer ribbon having a heat-fusible ink layer provided on the surface of a polyester base film and a heat-resistant protective layer. The heat-resistant protective layer comprises (1) a chlorinated product of a 4-methyl-1-pentene polymer or a derivative thereof and an amorphous linear saturated polyester or (2) at least one member selected from the group consisting of chlorinated products of acid-modified 4-methyl-1-pentene polymers and acid-modified 4-methyl-1-pentent/.alpha.-olefin copolymers.

  • Patent number: 4735860
    Abstract: A heat-resistant thermal transfer sheet comprising a base film provided on one surface thereof with a hot melt ink layer and with a heat-resistant protective layer on the other surface thereof. The heat-resistant protective layer is produced from a composition comprising (a) a thermoplastic resin having an OH or COOH group, (b) a polyamine or polyisocyanate, and (c) a thermoplastic resin, or a composition based on a silicone-modified resin. The heat transfer sheet of the present invention prevents sticking and blocking problems and makes it possible to carry out printing smoothly.
