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.
Claims18
A single layer of a light-curing, reactive, pressure-sensitive adhesive film of adhesive, comprising
- (a) at least one reactive monomer or reactive resin,
- (b) an initiator,
- (c) a photoredox catalyst,
- (d) a polymer obtained by radical polymerization of monomers containing carbon-carbon double bonds, wherein the monomers comprise N-vinyl compounds containing a nitrogen atom directly bonded to a vinyl group,
- and
- (e) a film-forming polymer.
