  • Publication number: 20060147702
    Abstract: The development of new compositions and new aromatic sulfur acrylate monomers results in improved hardcoat films, and improved optical films that contain the hard coat films. The films provide improved display systems when incorporated thereon. The combination of functionalized zirconia nanoparticles with multifunctional acrylate crosslinkers and high index of refraction aromatic sulfur acrylates, about 1.58 or greater, produces abrasion resistant hard coats that have relatively high refractive indices.

  • Publication number: 20060147674
    Abstract: 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 modifation 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.

Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.
