A radiation-curable composition in a liquid or solid form comprises at least one solid, non-crystalline radiation-transmissible material, dispersed in at least one cationic-curable or free-radical curable composition or mixture thereof. The solid, non-crystalline radiation-transmissible materials comprise glasses and other suitable materials that transmit (i.e., are transparent to) at least about 40% of radiation having a wavelength from about 180 to about 600 nanometers. The solid forms of the radiation-curable compositions of the invention are useful as powder coatings for coating decorative and functional objects and that would be cured by a thermal heating flow process followed by radiation exposure. The cured compositions of the invention are useful as coatings and inks for metal, paper, plastics, glass, ceramics, and wood, as adhesives, as sealants, and as composite materials and other articles and in biomedical and dental applications.
