PROBLEM TO BE SOLVED: To provide an active energy ray-polymerizable resin composition for optical three-dimensional molding, which can give a cured product with high accuracy by an optical three-dimensional molding method while reducing deformation such as warpage or swelling in a molding process, and which can be polymerized and cured by irradiation with various types of active energy rays to give resin cured products, and a firm 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 (I) having at least one hydroxyl group and no α,β-unsaturated double bond group in the molecule; an α,β-unsaturated double bond group-containing compound (A) having at least one hydroxyl group in the molecule; an α,β-unsaturated double bond group-containing compound (B) having at least one cyclic structure in the molecule; and an α,β-unsaturated double bond group-containing compound (J) except for the compound (A) and compound (B).SELECTED DRAWING: None |
