ABSTRACT:
Urethanes of hydroxybenzotriazoles and hydroxybenzophenones which can be chemically modified upon heating have been found useful in imparting weather resistance to plastic substrates when applied as part of a UV curable resin which can be subsequently heated after cure. UV curable resins containing such urethanes and the use of such resins to treat thermoplastic substrates are also described.
