PURPOSE: A UV-curable resin composition for glass or plastic optical fiber cladding is provided, to remove the stress due to the shrinkage in curing, to reduce the amount of viscosity increase, to save the use amount of a diluent in preparation of a resin and to minimize the light transmission loss. CONSTITUTION: The resin composition comprises (A) 40-95 parts by weight of the photopolymerizable acrylate oligomer prepared from the composition comprising 5-90 parts by weight of a polyol copolymer, 20-40 parts by weight of an acid anhydride, 5-50 parts by weight of an acrylate alcohol, 0.01-1 parts by weight of a polycondensation catalyst and 0.01-1 parts by weight of a polymerization inhibitor; (B) 5-60 parts by weight of a photopolymerizable monomer; (C) 0.5-20 parts by weight of a photoinitiator; and (D) 0.1-5 parts by weight of a leveling agent and an antifoaming agent.
