Radiation-curable catalysts are obtainable by reacting n A) 1 equivalent of a dihydric to hexahydric oxyalkylated C 2 -C 10 -alcohol with n B) from 0.05 to 1 equivalent of a dibasic to tetrabasic C 3 -C 36 -carboxylic acid or its anhydride and n C) from 0.1 to 1.5 equivalents of acrylic acid and/or methacrylic acid n and reacting the excess carboxyl groups with an equivalent amount of epoxide compound, and are used in radiation-curable coating materials. |
