  • Surface having a coating of a host multidentate ligand and a reversibly trapped lubricant
    Patent number: 5830577
    Abstract: The lubricant layer according to the present invention is used in a thin film magnetic recording medium in which a solid surface sliding at a high speed is required to retain its lubricating performance and abrasion resistance for a long period of time, comprising a host-guest complex composed of a lubricant molecule as a guest molecule and a multidentate ligand as a host compound to form the complex with the guest molecule.
    Type: Grant
    Filed: June 27, 1996
    Date of Patent: November 3, 1998
    Assignee: Mitsubishi Chemical Corporation
    Inventors: Hideki Murayama, Keiichiro Sano, Kazuhiko Sawada, Fumiaki Yokoyama, Haruhiko Ikeuchi, Yutaka Teranishi
