ABSTRACT:
The invention relates to biaxially oriented, co-extruded polyester films. Said films comprise a base layer which consists of at least 70% by weight of a thermoplastic polyester, preferably polyethylene terephthalate (PET) with a diethylene glycol and/or polyethylene glycol content greater than 1.3% by weight and have at least one matt outer layer and optionally additional intermediate layers. The films also contain at least one UV-absorber, preferably hydroxy benzotriazoles and triazines. The films are characterized by high UV-stability, no embrittlement after exposure to temperature, a matt surface devoid of unwanted clouding and excellent thermoforming properties and are, together with the molded bodies produced therefrom, suitable for numerous interior and exterior applications. The (matt) outer layers can be identical or different and contain a mixture or a blend of a component I which consists of PET homopolymers and/or copolymers and a component II which is a copolymer resulting from the condensation product of isophthalic acid, an aliphatic dicarboxylic acid and a sulfomonomer with a copolymerizable aliphatic or cycloaliphatic glycol.
