  • Laminated optical products and methods of making them
    Patent number: 11747532
    Abstract: Optical products are disclosed that include a polymer substrate; a composite coating, deposited on the polymer substrate; a permeating adhesive, which permeates the composite coating and is in contact with the polymer substrate; and a protective layer, secured to the composite coating by the permeating adhesive. The composite coating includes at least a first layer and a second layer, each of which is provided with a binding group component which together form a complementary binding group pair. The optical products exhibit improved resistance to delamination during storage and use.
    Type: Grant
    Filed: September 15, 2017
    Date of Patent: September 5, 2023
    Assignee: Southwall Technologies Inc.
    Inventors: Kevin C. Krogman, Lee Campbell Boman, Julius George Kozak, Kayur Ashwin Patel, Jeremy B. Stegall, Anthony Brian Port
