Abstract

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 by T-peel adhesion test, than the use of other conventional adhesion promotors.
