Wax And Resin In Transfer Layer Patents (Class 428/32.84)
  • Patent number: 9275559
    Abstract: An identification medium is optimized for displaying visible and excitable indicia. The medium includes a substrate having a color change layer, such as a direct thermal layer, and a patterned excitable layer placed over the color change layer. The color change layer produces the visible indicia. The excitable layer produces the excitable indicia. The excitable indicia is not easily readable under ambient light but becomes more easily readable under directed radiation, i.e., UV or IR light.

  • Patent number: 6790493
    Abstract: An aqueous coating formulation which forms a thermal transfer layer of a thermal transfer ribbon. This formulation comprises an aqueous emulsion of a thermoplastic resin and/or wax coemulsified with an epoxy curing agent. This emulsion can be combined with an aqueous dispersion of an epoxy resin. These coating formulations provide thermal transfer layers with reactive components that increase in molecular weight when heated during transfer to provide images with high scratch and smear resistance without organic solvents. The reactive components are maintained in separate phases within the same thermal transfer layer or separate thermal transfer layers until exposed to a thermal print head.
