  • Patent number: 9771491
    Abstract: The present invention provides a laminated film comprising a polyester film having a resin layer on at least one side thereof, wherein said resin layer contains at least metal oxide particles (A) having a number average particle diameter of 3 nm or more and 50 nm or less, and an acrylic resin (B), and a component (C1) derived from an oxazoline-based compound and/or a component (C2) derived from a melamine-based compound, and wherein said acrylic resin (B) contains a monomer unit (b1), a monomer unit (b2) and a monomer unit (b3). The present invention provides a laminated film which is excellent in transparency, suppression of interference pattern upon lamination of a high refractive index hard coat layer, adhesive property to a high refractive index hard coat layer, and adhesion under high temperature and high humidity conditions (adhesion under high temperature and high humidity conditions), at a low cost.

  • Patent number: 9604435
    Abstract: Provided is a multilayer film, in which a resin layer obtained using a resin (?) is provided on at least one surface of a polyester film, and which satisfies the conditions (I)-(IV) described below. (I) The resin layer has a thickness of 80-500 nm. (II) The resin layer has a pencil hardness of F or higher. (III) The multilayer film has a haze of 3.0% or less. (IV) The resin (?) is a resin that is obtained by heating a resin composition, which contains a resin (A) that has a hydroxyl group and an acryloyl group and a melamine compound (B) that has a methylol group, at 150° C. or higher.
