A curable composition is provided comprising a urethane (meth)acrylate oligomer, a urethane (urea) phosphonate ad-hesion promoter, optionally reactive diluents, and an initiator. The use of the urethane (urea) phosphonate adhesion promotor provides better ageing stability and adhesion, as measured b...
