A novel photo-curable resin composition. The resin composition capable of providing a three-dimensional object having excellent mechanical strength and high dimensional accuracy. The resin composition capable of providing a three-dimensional object with excellent stability in shape and properties using an optical fabricating process. The composition comprises (A) a cationic polymerized compound, (B) a cationic photo-initiator, (C) an ethylenically unsaturated monomer, (D) a radical photo-initiator, (E) a polyether polyol having on average about 3 or more hydroxyl groups and wherein at least 60 % by weight of the ethylenically unsaturated monomer having three or more ethylenically unsaturated bonds in one molecule. |
