  • Thermal transfer imprinting
    Patent number: 4581278
    Abstract: Thermal imprinting for example of one or more surfaces, using a heat transfer carrier and a release layer of pigmented, low molecular weight polyolefin. The imprint is made by bringing the transfer layer into contact with the surface of an object and applying heat. This releases the transfer layer to the surface being imprinted. When the transfer layer is required to have any significant thickness, it desirably includes a low melting point wax or resin to provide flexibility. The release characteristic can be improved by the inclusion of a further crystalline wax layer between the transfer layer and the carrier.
    Type: Grant
    Filed: July 14, 1983
    Date of Patent: April 8, 1986
    Assignee: Dennison Manufacturing Company
    Inventors: Edward S. Margerum, Norman A. Hiatt
  • Thermal imprinting of substrates
    Patent number: 4511602
    Abstract: Thermal imprinting of substrates, for example one or more surfaces of multi-dimensional objects, using a heat transfer film formed by a carrier and a release layer of pigmented, low molecular weight polyolefin. The imprint is made by bringing the transfer layer into contact with the surface of an object and applying heat. This releases the transfer layer to the surface being imprinted. When the transfer layer is required to have any significant thickness, it desirably includes a low melting point wax or resin to provide flexibility. The release characteristic can be improved by the inclusion of a further crystalline wax layer between the transfer layer and the carrier.
