Abstract
A radiation-curable liquid resin composition contains (A) an organopolysiloxane having a (meth)acryl group at either end of its molecular chain, containing at least 15 mol % of aromatic hydrocarbon groups based on the entire organic groups, and being free of a urethane bond, (B) a compound having at least one ethylenically unsaturated group in a molecule, and (C) a photopolymerization catalyst. The composition has a low viscosity and cures into a product having a low Young's modulus and experiencing a less change of Young's modulus at low temperatures. The composition is useful as a primary coating for optical fibers.
