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 0.1 to 10 wt.% of a) at least one co-polymerizable photoinitiator in accordance with Formula (I): wherein: R<1> is NH, CH<2>, S or O; R<2> to R<9> are independently selected from H, OH, SH, halide, CN, C<1>-C<6> alkyl, C<1>-C<6> alkoxy, C<1>-C<12> alkoxyalkyl, COOH, SR<10>, COOR<10>, N(R<10>)<2> or N(R<10>)<3>Q; each R<10> is independently selected from C<1>-C<6> alkyl or C<6>-C<18> aryl; and, Q is halide, acetate, phosphate, sulphate or nitrate, subject to the proviso that j of the radicals R<2> to R<9> are a radical possessing ethylenic unsaturation, wherein j is an integer of from 1 to 3, preferably 1 or 2; and, from 90 to 99.9 wt.% of b) at least one ethylenically unsaturated non-ionic monomer which does not bear an epoxide group or a moiety decomposable under photo-irradiation to form a radical. <img class="EMIRef" id="19d7e882-e597-40f6-af76-6a048d9c5ca2-ia01" />
