<p>Liquid mixtures which are curable by exposure to ultraviolet light when appropriately photosensitized and are suitable as coating compositions are provided by etherifying a polyepoxide with an at least 25% stoichiometric excess of an hydroxy alkyl ester of an alpha, beta-monothylenically unsaturated monocarboxylic acid, especially hydroxy ethyl acrylate. The unreacted hydroxy alkyl ester is than consumed by reaction with at least 1 molar equivalent of a monoanhydride, such as a monoepoxide, a lactone, or a monoisocyanate.</p> |
