PROBLEM TO BE SOLVED: To provide a photo-curable resin composition having a short defoaming time of produced air bubbles, shaping a three-dimensional formed material without residual air bubbles, having excellent coating properties and forming a uniform thin layer on the top surface, etc., of a cured resin layer without causing cissing and to provide the three-dimensional formed material having an excellent appearance state and good mechanical strength wthout the residual air bubbles. SOLUTION: The resin composition is the photo-curable resin composition used for an optical stereolithographic method and comprises [A] a cationic polymerizable organic compound, [B] a cationic photopolymerization initiator and [C] a (co)polymer obtained by (co)polymerizing a monomer containing an acrylic or a methacrylic ester. The three-dimensional formed material is shaped by the optical stereolithographic method using the resin composition. COPYRIGHT: (C)2005,JPO&NCIPI
