摘要：
Radiation-curable contact adhesives containing (A) oligomeric or polymeric reaction products of (a) diisocyanates, (b) polyesterols and/or polyetherols, (c) optionally C.sub.2 -C.sub.50 -diols, (d) C.sub.2 -C.sub.20 -hydroxyalkyl (meth)acrylates and (e) monohydroxyalkylcarboxylic acids in defined weight proportions and (e) monovinyl compounds in an amount of 2-90% by weight, based on A+B, produce contact adhesive layers of particularly high surface tackiness and particularly high cohesion.
