PROBLEM TO BE SOLVED: To obtain a liquid curable resin composition that has a high Young's modulus and yet an excellent flex resistance and is suitable as an optical fiber tape material. SOLUTION: The liquid curable resin composition comprises (A) a urethane (meth)acrylate having a structure derived from a polypropylene glycol having a number-average molecular weight of 500-4,000, (B) a urethane (meth)acrylate having a bisphenol structure and (C) a compound containing one ethylenic unsaturated group. The component (C) comprises 40-80 mass% of isobornyl (meth)acrylate based on 100 mass% of the total of the component (C). COPYRIGHT: (C)2009,JPO&INPIT
