Abstract
A novel photo-curable resin composition. The resin composition capable of providing a cured product having excellent mechanical strength, high dimensional accuracy, and excellent toughness. The resin composition is capable of providing a cured product which experiences little change in mechanical strength over time. The resin composition is capable of forming, by photo-fabricating, a three-dimensional object which can be used for a long period of time in a humid atmosphere. The composition comprises, (A) an epoxy compound having a cyclohexene oxide, (B) a cationic photo-initiator, (C) an ethylenically unsaturated monomer, (D) a radical photo-initiator, and (E) a polyol.
