PROBLEM TO BE SOLVED: To provide an active energy ray-polymerizable resin composition that can give a cured product having high accuracy by an optical three-dimensional molding process while reducing deformation during molding such as warpage or swelling and that can give a resin cured product polymerized and cured at a fast rate by irradiation with various active energy rays, and to provide a strong and robust three-dimensional molded object.SOLUTION: An active energy ray-polymerizable resin composition for optical three-dimensional molding is provided, which comprises a compound (A) having a molecular weight of 500 or more and at least one 2,2,6,6-tetramethylene piperidine skeleton in the molecule, an α,β-unsaturated double bond group-containing compound (B) having at least one hydroxyl group in the molecule, and an α,β-unsaturated double bond group-containing compound (C) having no hydroxyl group in the molecule.SELECTED DRAWING: None |
