  • Publication number: 20160208130
    Abstract: A high-hardness hard coat film having a reduced degree of curling and an ionizing ray polymerizable resin composition for forming the hard coat layer of such a hard coat film are provided. The hard coat film includes a resin film and a hard coat layer disposed on the surface of the resin film. The hard coat layer is formed of a cured product of a photopolymerizable composition containing an acrylic component, a hyperbranched acrylate resin, a silicone component, and silica particles. The cured product is produced by exposure to ionizing rays.

  • Patent number: 8383212
    Abstract: An alignment film or a phase difference device with small shift from a desired alignment direction and a display unit including the same are provided. The alignment film includes: a substrate having a plurality of grooves extending in a specific direction on a surface; and a non-alignment thin film formed along a surface of the plurality of grooves. The phase difference device includes: an alignment film that has a substrate having a plurality of grooves extending in a specific direction on a surface and a non-alignment thin film formed along a surface of the plurality of grooves; and a phase difference layer that is provided being contacted with a surface of the non-alignment thin film, and includes a liquid crystal material that is aligned along an extending direction of a dent formed by the non-alignment thin film and is polymerized.

  • Publication number: 20110164322
    Abstract: A UV-curable resin material composition coating liquid is provided and includes a UV-curable resin material composition dissolved or dispersed in a nonpolar solvent or a substantially nonpolar mixed solvent. The UV-curable resin material composition includes a monomer and/or an oligomer thereof that have two or more (meth)acryloyl groups, and affinity to a nonpolar solvent, modified hollow silica fine particles altered to have affinity to a nonpolar solvent by introduction of an aliphatic hydrocarbon group to surfaces of hollow silica fine particles, and a polymerization initiator.
