Beschreibung
Zusammenfassung:	The present application is directed to a copolymer obtained by free radical polymerization, said copolymer comprising, based on the total weight of monomers:from 0.01 to 10 wt.% of a) at least one co-polymerizable photoinitiator having an ethylenically unsaturated group and a moiety that is decomposable under photo-irradiation to form a radical;from 0.01 to 10 wt.% of b) at least one epoxy (meth)acrylate monomer having at least one (meth)acrylate group and at least one epoxide group; and,from 80 to 99.98 wt.% of c) at least one ethylenically unsaturated monomer which does not bear an epoxide group or a moiety decomposable under photo-irradiation to form a radical.The present application is further directed to a material which is crosslinkable under photoirradiation, said material comprising: a copolymer as defined above; and, at least one ionic photoacid generator (PAG).
