  • Hydrogel laminate, bandages and composites and methods for forming the same
    Patent number: 6468383
    Abstract: The present invention provides processes by which a polymeric hydrogel can be securely adhered to a substrate to form a hydrogel laminate with greatly improved delamination resistance. The laminate is formed by casting onto a polymeric adhesive-coated substrate an aqueous solution of hydrophilic polymer, then exposing this composite to ionizing radiation which cross-links the hydrophilic polymer to form a hydrogel and also induces copolymerization of the hydrophilic polymer and the adhesive polymer.
    Type: Grant
    Filed: March 9, 2001
    Date of Patent: October 22, 2002
    Assignee: Johnson & Johnson Consumer Companies, Inc.
