  • Smudge resistant nanocomposite hardcoats and methods for making same
    Patent number: 7101616
    Abstract: Nanocomposite hardcoats having smudge and abrasion resistant properties are disclosed. Latent reactive nanoparticles are contained within a binder phase to form a nanocomposite. When deprotected and treated with a reactive fluorochemical, nanoparticles present at the surface of the nanocomposite become permanently modified and impart smudge resistance. The nanocomposite hardcoats may optionally be supported on a primary substrate.
    Type: Grant
    Filed: September 6, 2002
    Date of Patent: September 5, 2006
    Assignee: 3M Innovative Properties Company
    Inventors: David S. Arney, Judith M. Invie, Alexander B. Doust
