Abstract of  WO2016186877 (A1)：

Presently described are methods of preparing a pressure sensitive adhesive composition comprising providing a non-aqueous pressure sensitive adhesive comprising a (meth)acrylic copolymer comprising epoxy-functional groups; adding a chlorinated triazine crosslinker to the pressure sensitive adhesive; and coating the pressure sensitive adhesive onto a substrate. In some embodiments, the method may further comprise contacting the pressure sensitive adhesive to a second substrate. The method further comprises exposing the pressure sensitive adhesive to actinic radiation to crosslink the epoxy-functional groups by means of the triazine crosslinker. The step of exposing can occur at the time of manufacture (e.g. of a pressure sensitive adhesive coated articles such as a tape) or at the time of use. Also described are non-aqueous pressure sensitive adhesive compositions and adhesive-coated articles.
