PROBLEM TO BE SOLVED: To provide a liquid curable resin composition for an optical fiber coating, the composition resulting in a cured product with a high n value (dynamic fatigue coefficient) by curing with radiation. SOLUTION: The liquid curable resin composition contains (A) an alkoxysilane compound by 0.1 to 10 mass% and (B) an organic sulfonic acid compound by 0.01 to 1 mass%, and further contains (C) urethane (meth)acrylate by 35 to 85 mass% and (D) a reactive diluent copolymerizable with the component (C) by 1 to 60 mass%.
