Abstract
Highly pigmented liquid epoxide coating compositions containing one or more liquid epoxides, up to 60% by weight of pigment, one or more carboxylic acid anhydrides and specified diazonium salts of Lewis acids are converted to solid materials with substantially no weight loss following a relatively short exposure to ultraviolet radiation. The heretofore unattainable objective of a light-curable, substantially solventless coating composition containing sufficient pigment to obtain acceptable levels of hiding power is achieved by the presence of the carboxylic acid anhydride.
