Abstract
The invention relates to a UV-cross-linked, polyacrylate-based adhesive mass that has high adhesive force and high cohesion and that can be produced by means of a hot-melt process with subsequent cross-linking. This is achieved by providing an adhesive mass that can be obtained by cross-linking a composition, which comprises at least one poly(meth)acrylate having a weight-average molar mass Mof at least 100,000 g/mol and at least one polyfunctional α-cleaver and is characterized in that the composition contains at least one adhesive-force-increasing resin having a weight average molar mass Mof at most 30,000 g/mol, which resin can be obtained by polymerizing a monomer composition M1, comprising at least one compound according to formula (I) HC═C(R)(COOR), wherein Rrepresents a hydrogen atom or a methyl group and Rrepresents a hydrogen atom or a functionalized or non-functionalized C-Calkyl group.
