  • Publication number: 20150146287
    Abstract: The present invention relates to a multilayer structure comprising A) a functional film comprising a VIS/IR-reflecting metal layer on a carrier film, wherein the carrier film can be in single-layer form or in the form of a UV- and/or UV/VIS-reflecting multi-ply layer, and at least one adhesive layer, and optionally at least one scratch-resistant layer, B) a functional layer comprising a layer of metal nitrides, metal oxides or semimetal oxides, mixed oxides or metals, wherein the layer can additionally have a coating, C) optionally a carrier film, D) optionally an adhesive layer, E) a substrate layer. By means of such a multilayer structure it is possible, in the adhesive bonding of thin functional films by means of a PSA (“pressure sensitive adhesive”) to thermoplastics such as, for example, polycarbonate, largely to avoid blistering of the adhesively bonded film in the case of outside use (in a changing climate).
