More Information
Summary:The present invention relates to urethane(meth)acrylate resins obtained from the reaction, in a first step, of at least one polyisocyanate (I) with at least one compound (II) containing at least two reactive groups capable to react with isocyanate groups and at least one (meth)acrylate (III) containing essentially one reactive group capable to react with isocyanate groups, and, in a subsequent step, reacting the product obtained from the first step with at least one polyisocyanate (IV) different from the poly-isocyanate (I) used in the first step, and their use for making radiation cured pressure sensitive adhesives.
