  • HARD COAT FILM
    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.

  • Antireflection Film
    Publication number: 20100118406
    Abstract: Disclosed is an antireflection film having high antifouling property. Specifically disclosed is an antireflection film comprising a transparent base, a high refractive index layer and a low refractive index layer. The low refractive index layer is made of a cured product of a polymerizable composition which contains hollow fine particles such as hollow silica particles, a modified silicone compound, and a second resin component such as a polyfunctional (meth)acrylate.
