Abstract
Hotmelt contact adhesives which are crosslinkable with UV light in the air are based on copolymers which contain tetrahydrofurfur-2-yl (meth)acrylate and/or N-2-tetrahydrofurfuryl (meth)-acrylamide and/or alkoxyalkyl (meth)acrylates and/or N-alkoxyalkyl (meth)acrylamides as copolymerized units and added benzophenone and/or benzophenone derivatives as photosensitizers.
