PAT 88 181 04 Nov. 1988 (0830z) of the disclosure Liquid, radiation-curable coating composition for coating glass surfaces The present invention relates to a liquid, radiation-curable coating composition which contains A) 56 to 89% by weight of at least one diethylenically unsaturated polyurethane optionally containing urea groups, B) 10 to 30% by weight of at least one ethylenically unsaturated monomer, C) 0.5 to 8% by weight of at least one photoinitiator, and D) 0.05 to 6% by weight of N-.beta.-aminoethyl-.gamma.-aminopro-pyltrimethoxysilane, .gamma.-aminopropyltrimethoxysilane, N-methyl-.gamma.-aminopropyltrimethoxysilane or triaminomodified propyltrimethoxysilane, the sum of components (A) to (D) in each case being 100% by weight, and all % by weight data being based on the coating composition. These coating agents are employed for coating glass surfaces, in particular optical glass fibers, and are distinguished by good adhesion, even on exposure to moisture. |
