  • Multilayered film made of (meth)acrylate copolymer and polycarbonate
    Patent number: 7682698
    Abstract: The invention relates to a multilayer film encompassing at least one upper layer a) and one middle layer b) composed of (meth)acrylate copolymers, and also a backing layer c) composed of polycarbonate, where the upper layer a) comprises a light stabilizer and is composed of a (meth)acrylate copolymer which can form semicompatible mixtures with the polycarbonate of the backing layer c), where a test specimen produced from a mixture composed of 20% by weight of (meth)acrylate copolymer and 80% by weight of polycarbonate has a tensile strain at break of at least 75% (ISO 527-2) at 23° C.
    Type: Grant
    Filed: May 7, 2009
    Date of Patent: March 23, 2010

  • Multilayered film made of (meth)acrylate copolymer and polycarbonate
    Patent number: 7585565
    Abstract: The invention relates to a multilayered film comprising at least one upper layer a), a middle layer b) made of (meth)acrylate copolymer, and a supporting layer c) made of polycarbonate. Upper layer a) contains a light-stability agent and is made of a (meth)acrylate copolymer that, together with the polycarbonate of supporting layer c), can form partially compatible mixtures. A test piece, which is made from a mixture consisting of 20% by weight of (meth)acrylate copolymer and 80% by weight of polycarbonate, has a breaking elongation (ISO 527-2) of at least 75% at 23° C. The middle layer b) contains a colorant and, optionally, a light-stability agent and is made from an identical or different (meth)acrylate copolymer that, together with the polycarbonate of supporting layer c), can form partially compatible mixtures.
