A liquid curable resin composition exhibiting superior storing stability and suitable for use as a material for optical fiber ribbon matrix, a bundling material, and a material for up-jacketing fibers. The composition contains a first polydimethylsiloxane compound which contains: (i) at least two urethane bonds; (ii) an unreactive organic group attached to at least one end of the first polydimethyl-siloxane; and (iii) a (meth)acrylol group attached to at least one end of the first polydimethylsiloxane, and a second polydimethylsiloxane compound which contains: (i) at least two urethane bonds and (ii) an unreactive organic group attached to at least one end of the second polydimethylsiloxane, and optionally a third polysiloxane compound which does not contain urethane bonds. |
