PROBLEM TO BE SOLVED: To provide a radiation-curable liquid resin composition for optical three-dimensional molding, from which an optically molded product excellent in toughness and heat resistance can be obtained.SOLUTION: A radiation-curable liquid resin composition for optical three-dimensional molding comprises (A) a compound having a carbonate group, two or more (meth)acryloyl groups and no urethane bond, (B) a cation polymerizable compound, (C) a photocationic polymerization initiator, (D) a radical polymerizable compound, and (E) a photoradical polymerization initiator. A preferred example of the (A) component is a compound having two or more carbonate groups and three or more (meth)acryloyl groups. A preferred structural moiety included in the chemical structure of the (A) component is, for example, a branched structure and an aromatic structure. |
