Title: Smudge resistant nanocomposite hardcoats and methods for making same

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.
