Abstract

The invention relates to an adhesive containing two components A and B, whereby component A comprises both a functional group which can be polymerized by means of irradiation with UV beams as well as at least one functional group which is able to react with a compound having at least one acidic hydrogen atom and component B comprises at least two functional groups which can be polymerized by means of irradiation with UV beams or with electron beams. The adhesive is suitable for the production of composite materials and exhibits a high flexibility with a good initial bonding.
