Abstract: Disclosed is a pressure-sensitive adhesive composition which exhibits good adhesive forces, in particular on polar adhesive substrates, and good shear strength, and a significant proportion of which can be produced from bio-based raw materials. The pressure-sensitive adhesive composition comprises: at least one copolymer which can be traced to a monomer composition comprising a) 45-75 wt. % of at least one monomer selected from i-amyl acrylate, n-heptyl acrylate, and 2-octyl acrylate, b) 24-50 wt. % of at least one alkyl (meth)acrylate, the alcohol component of which has 1 to 4 carbon atoms, and c) 0.5 to 10 wt. % of acrylic acid; and at least one adhesive force-enhancing resin. Also disclosed is an adhesive tape comprising a carrier material and the pressure-sensitive adhesive composition; and the use of the pressure-sensitive adhesive composition or the adhesive tape to produce adhesive bonds in electronic, optical and/or precision mechanical devices.

Abstract: The present invention relates to a light-curing, reactive, pressure-sensitive adhesive film of adhesive. With the film of adhesive of the invention, structural bond strengths can be achieved. The film of adhesive comprises (a) at least one reactive monomer or reactive resin, (b) an initiator, (c) a photoredox catalyst, (d) a polymer of monomers comprising N-vinyl compounds and (e) a film-forming polymer.
