    Abstract: The present application is directed to an adhesive tape comprising: i) a first release liner; and, ii) a pressure sensitive adhesive layer disposed on said first release liner, wherein said pressure sensitive adhesive layer is obtained by curing an adhesive composition comprising: a) an acrylic base copolymer obtained from a monomer mixture comprising at least one C1-C12 alkyl ester of (meth)acrylic acid and at least one acid monomer selected from acrylic acid, methacrylic acid, maleic acid, fumaric acid and itaconic acid; b) a metal chelate cross-linking agent; c) at least one tackifying resin; d) an organic solvent; and, optionally e) additives. The adhesive tape optionally comprises iii) a second release liner which is disposed on that side of said pressure sensitive adhesive layer opposite to said first release liner.

    Abstract: 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).
