This is achieved with an adhesive tape comprising at least one foamed layer and at least one adhesive compound layer, wherein the adhesive compound layer contains at least one poly(meth)acrylate, and the poly(meth)acrylate is cross-linked with at least one covalent and at least one coordinative cross-linker.
