A liquid curable resin composition containing urethane bond at a concentration of 2.0.times.10.sup.-3 mole/gm or more and comprising: (a) a urethane (meth)acrylate having at least three cyclic structures in the molecule; (b) a polymerizable mono-functional vinyl monomer of which the homopolymer has a glass transition point of 50.degree. C. or more; and (c) a polymerization initiator. The liquid curable resin composition possesses a high Young's modulus, exhibits very little contraction stress, has high tenacity and good curing characteristics. Along with these superior characteristics, the high reliability of the composition makes it a suitable coating material for optical fiber. Furthermore, since the resin composition possesses a high Young's modulus and high tenacity, it is also useful as a protective coating material for metals, plastics, wood, ceramics, glass, and the like.
