Liquid curable resin composition
First Claim
1. A liquid radiation curable resin composition comprising a polydimethylsiloxane compound which has (i) at least two urethane bonds in one molecule, (ii) an unreactive organic group at at least one of the ends of the molecule, and (iii) a radical curable ethylenically unsaturated group at the other end of the molecule.

Abstract
A liquid radiation curable resin composition comprising a polydimethylsiloxane compound which has (i) at least two urethane bonds in one molecule, (ii) an unreactive organic group at at least one of the ends of the molecule, and (iii) a radical curable ethylenically unsaturated group at the other end of the molecule. The resin composition exhibits superior shelf life in a liquid state and produces cured products having slippery surface. It is suitable as a coating material for optical fibers.
