  • Heat fixing paper or sheet
    Patent number: 5968634
    Abstract: A paper or transparency receiving toner to be fixed by heat has an ionomeric resin on its outer surface. For universal application, the outer layer is a blend of non-ionomeric resin, such as styrene acrylate copolymer, and an ionomer, which permits the material of the toner to molecularly intermingle with the blend during heat fixing. Irradiation raises the melting point of the ionomeric resin to prevent delamination. The resulting printing is strongly bonded to the substrate and is of excellent quality.
    Type: Grant
    Filed: June 10, 1997
    Date of Patent: October 19, 1999
    Assignee: Lexmark International, Inc.
    Inventors: Jan Rose Heeg, Rolfe Frank Kruckas, Ashok Murthy, Stephen Todd Olson, Jeanne Marie Saldanha-Singh, Rita Sharma, Ajay Kanubhai Suthar, Richard Barber Watkins, Joe Williams Woods
