An adhesive composition which is switchable under irradiation to change from a tacky to a less tacky state which includes a switchable polymer. The polymer comprises a backbone polymeric moiety bound to a plurality of curable moieties, each of which comprises a free-radically active group and has an amine functionality. Also, the switchable polymer, processes for producing such polymers and compositions, and switchable adhesive articles comprising the adhesive compositions, such as light-switchable pressure sensitive adhesive dressings, and methods of using such articles. |
