ABSTRACT:
The invention relates to a synthetic resin based on an acrylate copolymer containing epoxide groups and having a number average molecular weight of 1,000 to 30,000. The acrylate copolymer comprises (a) 20 to 90% by weight of an alkyl acrylate having 1 to 18 carbon atoms in the alkyl radical and/or a methacrylate having 1 to 20 carbon atoms in the alkyl radical, (b) 5 to 40% by weight of a hydroxyalkyl acrylate and/or methacrylate and (c) 5 to 40% by weight of glycidyl acrylate and/or methacrylate and/or one other olefinically unsaturated, polymerizable compound carrying an epoxide group, the total amount of components a, b and c being 100%. The hydroxyl groups of the acrylate copolymer have been reacted before or after the copolymerization was carried out at least partially with a partially blocked diisocyanate and/or polyisocyanate.
