ACTIVE ENERGY RAY-CURING RESIN COMPOSITION AND OPTICAL PRIMARY COATED FIBER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-curing resin composition to be used as for outermost layer of a single optical coated fiber having three or more coating layers, and having excellent surface smoothness, storage stability and drawing property, and to provide a single optical coated fiber having excellent drawing property by using the above composition.;SOLUTION: The actinic ray-curing resin composition is used to form the outermost layer (Z) of an optical coated fiber having three or more coating layers in which the outermost layer (Z) in the coating layers has 70 to 500 μm film thickness, and the composition comprises a radical polymerizable compound and a silicone compound (D1) having 10,000 to 300,000 number average molecular weight and ≤20% modification rate.;COPYRIGHT: (C)2006,JPO&NCIPI
