<p>Coating compositions, hardenable by exposure to high-energy radiation such as beta -rays, comprising, as the radiation-hardenable binder component thereof, a mixture of (a) 40 to 90 percent, by weight of said mixture, of an unsaturated polyester having free-radical polymerizable olefinic unsaturations in a position alpha , beta to an ester carbonyl group, and (b) 60 to 10 percent, by weight of said mixture, of a monomer component comprising at least 80 percent by weight of alkoxyalkyl esters of acrylic acid or methacrylic acid or mixtures of said esters with up to an equal amount by weight of hydroxyalkyl esters of acrylic acid or methacrylic acid.</p> |
