<p>PROBLEM TO BE SOLVED: To provide a resin composition for optical three-dimensional molding which makes it possible to obtain cured products having a small deformation with time, and further having excellent toughness and temporal stability, wherein the resin composition is irradiated with various active energy rays to obtain resin cured products capable of polymerization curing, thereby providing a strong and robust three-dimensional molded article.SOLUTION: A resin composition for optical three-dimensional molding comprises (A) an oligomer at least having one or moreα,β-unsaturated double bond group and (B) anα,β-unsaturated double bond group-containing compound having a ring structure of three or more rings (excluding one corresponding to the oligomer (A) and excluding one directly bonded to anα,β-unsaturated double bond group), in a molecule, as an essential component.</p> |
