  • Patent number: 5679461
    Abstract: A thermo-sensitive transfer recording materials comprising a base sheet, an ink layer and a heat-resistant lubricating layer. The heat-resistant lubricating layer is made of either a polymer compound obtained by reaction between a hydrocarbon compound having at least two hydroxyl groups in one molecule and/or a silicone compound having a hydroxyl group and an isocyanate compound having at least two isocyanate groups in one molecule, or a polymer compound obtained by reaction between a silicone compound having an amino group and an isocyanate compound having at least two isocyanate groups in one molecule.
    Type: Grant
    Filed: November 12, 1996
    Date of Patent: October 21, 1997
    Assignee: Sony Corporation
    Inventors: Rikio Kobayashi, Motohiro Mizumachi

  • Patent number: 5294484
    Abstract: Video printing paper used for a video printer is disclosed. A receiving layer comprising a polymeric material is formed on a surface of the video printing paper. Polyvinyl aromatic carboxylic acid ester or copolymer of it is used for the receiving layer. In the receiving layer, resin compatible with the polyvinyl aromatic carboxylic acid ester or its copolymer may also be used by 50 percent by weight or less. It is also possible to add a compound enhancing the dyeing property to the receiving layer. The compound for enhancing the dyeing property are exemplified by ester compounds and urethane compounds. This enables formation of an image superior in light resistance and weather resistance.
