  • Curable compositions and method for curing such compositions
    Patent number: 4108747
    Abstract: Cationically polymerizable compositions are provided, such as epoxides, vinyl ethers, and N-vinyl compounds having an effective amount of aryl onium trifluoromethane sulfonate salts, such as a triphenyl sulfonium trifluoromethane sulfonate and diphenyliodonium trifluoromethane sulfonate. The curable compositions are polymerizable under ultraviolet radiation. In addition to being used as adhesives, encapsulents and in coating applications, the aforementioned curable compositions can be employed as photoresists and as printing inks.
