An extruded matt foil has at least one layer in which glass beads are uniformly distributed in a polymer matrix with at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).

Extruded matt foil with improved mechanical properties and a high weathering resistance

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&#xb0; C., the middle layer b) comprises a dye and, where appropriate, a light stabilizer, and is composed of an identical or different (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&#xb0; C., and the backing layer c) is composed of polycarbonate which can, where appropriate, comprise up to 30% by weight of the material of the layers a) and b). The invention also relates to the production and uses of the multilayer film, and also to semicompatible polymer mixtures composed of (meth)acrylate copolymers and polycarbonate.

Multilayered film made of (meth)acrylate copolymer and polycarbonate

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&#xb0; 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. 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&#xb0; C., and the supporting layer c) is made of polycarbonate that, optionally up to 30% by weight of the material of the layers, can contain a) and b). The invention also relates to the production and uses of the multilayered film and to partially compatible polymer mixtures consisting of (meth)acrylate copolymer and polycarbonate.

The invention relates to a polymer mixture based on the (meth)acrylate (co)polymer components a), b), c), and/or d) according to claim 1, where a test specimen produced from the polymer mixture simultaneously has the following properties:
