The above-described composition comprises a compound with at least 2 cyclic carboxylic acid anhydride groups per molecule, a compound with at least 2 epoxide groups per molecule and a hydroxyle group containing acrylate copolymerizate. The composition is obtained from a1) 10 to 60% by weight, preferably 15 to 60% by weight of acrylate and/or methacrylate resine with 2 to 14 carbon atoms in the alkyl residue, a2) more than 3 to 30% by weight, preferably 5 to 25% by weight of monomers with at least 2 polymerizable olefinic-unsaturated double bonds and a3) 15 to 82% by weight, preferably 40 to 70% by weight of other polymerisable monomers with an olefinic-unsaturated double bond, whereby the sum of the components a1, a2 and a3 amounts to a 100% by weight.
