Abstract
The present disclosure provides an ionically crosslinkable composition comprising a (meth)acrylate copolymer component having pendant acid functional groups and pendant photobase functional groups. On exposure to light, the pendant photobase group photolyzes to provide a pendant amine group, that ionically crosslinks the copolymer.
