PCT No. PCT/EP92/02699 Sec. 371 Date May 26, 1994 Sec. 102(e) Date May 26, 1994 PCT Filed Nov. 24, 1992 PCT Pub. No. WO93/11080 PCT Pub. Date Jun. 10, 1993.The present invention is directed to a beam-curable coating composition for coating glass surfaces, particularly, optical glass fibers. The resultant coatings show slight or no loss of adhesion after exposure to moisture. The coating composition includes ethylenically unsaturated polyurethane, ethylenically unsaturated monomer, photoinitiator and a silane compound. The silane compound is an azidosilane and is added to improve adhesion of the coating agents exposed to moisture. Optionally, aminoalkoxysilanes may also be included.
