TRANSPARENT DECORATABLE MULTILAYER FILM

摘要

The invention relates to a multilayer film containing the following layers: I An upper layer made of a polyamide moulding compound that is transparent in the selected layer thickness, and II a lower layer made of a polyamide moulding compound containing the following components: (a) 70 to 99 wt. % of a polyamide selected from a) polyamides that can be produced from lactam monomers or the corresponding ?-aminocarboxylic acids with 6, 7, 8, 9, 10, 11 or 12 carbon atoms, (ß) polyamides based on diamine and dicarboxylic acids with between 6 and 18 carbon atoms in each case, ?) polyamide elastomers that can be produced from oligomeric difunctional building blocks based on one of the polyamides specified under (a) and (ß) and a difunctional oligoalkylene glycol, d) copolyamides that can be produced from a component consisting of 50 to 99.9 mol. % of a lactam monomer or the corresponding ?-aminocarboxylic acid with 6, 7, 8, 9, 10, 11 or 12 carbon atoms or an essentially equimolar mixture of a linear aliphatic diamine and a linear aliphatic or aromatic dicarboxylic acid with between 6 and 18 carbon atoms in each case, and a component consisting of 0.1 to 50 mol. % of the combination of a diamine and a dicarboxylic acid, where either the diamine or the dicarboxylic acid or both differ from, respectively, the diamine used in the other component and the dicarboxylic acid used in the other component, or of another lactam; (b) 1 to 30 wt. % of a copolymer containing units of the following monomers: a) 20 to 94.5 wt. % of one or more a-olefins with between 2 and 12 carbon atoms, (ß) 5 to 79.5 wt. % of one or more acrylic compounds, ?) 0 to 50 wt. % of an olefinically unsaturated epoxide, carboxylic anhydride, carboxylic imide, oxazoline or oxazinone. The film has good printing compatibility, good bonding properties and good transparency, and can for example be used as a top coating for skis.
