    摘要: The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modification of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.

    摘要: Optical films are described comprising a color shifting film comprising a matte surface layer; and light control microstructured layer disposed proximate the color shifting film. The optical film may comprise a matte layer disposed on a major surface of the color shifting film and the light control micro structured layer disposed on the color shifting film at an interface that is free of adhesive. Alternatively, the optical film may comprise a film stack comprising a light control film having a light control microstructured layer, a color shifting film, and an adhesive layer between the light control film and color shifting film. In some embodiments, the matte layer comprises matte particles. In other embodiments, the matte layer comprises a plurality of microstructures and no greater than 50% of the microstructures comprise embedded matte particles. In some embodiments, the microstructures are substantially free of embedded matte particles.
