Abstract

The invention relates to an adhesive tape comprising at least one layer of a pressure-sensitive acrylate adhesive comprising a polymer component and at least one additive, where the polymer component is composed of one or more copolymers each based on the following monomers: a) from 5 to 35% by weight of one or more monomers containing hydroxy groups and having a copolymerizable double bond; b) from 0 to 50% by weight of one or more acrylate and/or methacrylate monomers each having at least one amide group, urethane group, urea group, or carboxylic anhydride unit and/or ethylene glycol unit, c) from 15 to 95% by weight of an alkyl (meth)acrylate, where the alkyl moiety has from 1 to 14 carbon atoms, where the pressure-sensitive acrylate adhesive comprises one or more 2-(2H-Benzotriazol-2-yl) derivatives admixed as additive; and also a corresponding adhesive.
