Abstract
Abstract Highly reactive resin compositions that can be cured by UV-light and contain an unsaturated polyester with Beta , gamma ethylenically unsaturated ether groupings, one or more ethers selected from the alkyl, cycloalkyl, aralkyl and alkenyl ethers of N-methylolacrylamide and of N-methylolmethacrylamide, and a photoinitiator.
