Abstract
Abstract A cathode-ray tube-yoke combination comprises a cathode-ray tube having a glass envelope and a yoke fixedly positioned on the envelope with a body of cured polymeric material. The novel composition of the polymeric material comprises a UV-curable adhesive and UV-transmissive particles of a suitable material in an amount sufficient to accelerate the curing of the adhesive. A method to accelerate the curing is also described.
