Bromine-containing radiation curable acrylates and methacrylates

摘要

Bromine-containing urethane (meth)acrylate oligomers which are useful in the field of radiation curable coatings wherein flame redardancy, compatibility with acrylic monomers and other oligomers, and high refractive indices are desired. Coatings and adhesives prepared from the oligomers have good refractive indices. The oligomers are obtained by reacting (A) one or more polyisocyanates, (B) one or more hydroxy functional (meth)acrylates, and (C) one or more bromine-containing alcohols.
