  • Curable topcoat composition and methods for use
    Patent number: 6187129
    Abstract: A cutable topcoat composition and apparatus useful for preparing stable data carrying devices, such as multi-layered laminates, and methods for preparing and using the composition. The composition includes a polymerizable composition and a polymeric binder. The polymerizable composition includes hard and flexible polymerizable subunits in a ratio that optimizes flexibility while retaining good adhesion and plasticizer resistance. In a preferred embodiment, a polymerization initiator is also included in the composition. Optionally, a chain transfer agent may also be added to the composition. The composition is substantially plasticizer free. The methods of using the composition include incorporating the composition into a topcoat film useful for storing the topcoat composition prior to use in preparing data-carrying devices, such as cards.
    Type: Grant
    Filed: August 11, 1999
    Date of Patent: February 13, 2001
    Assignee: DataCard Corporation
    Inventors: Utpal R. Vaidya, Felix P. Shvartsman, Robert Sells, Bryan L. Baab
