Abstract
A non-aqueous coating composition based on an oxidatively drying alkyd resin and a photo-initiator. An acid or latent acid and one or more compounds of the group of vinyl ethers, acetals, and alkoxysilanes which are reactive in the presence of an acid are incorporated into the coating composition. The vinyl ethers, acetals, and alkoxysilanes preferably are covalently bounded to the alkyd resin. The ratio of the number of oxidatively drying groups present in the alkyd resin to the number of groups reactive in the presence of an acid preferably is in the range of 1/10 to 15/1. The acid preferably is the phosphoric acid dibutyl ester.
