Active energy ray polymerizable resin composition for optical three-dimensional shaping, and three-dimensional shaped article

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-polymerizable resin composition for stereolithography, which can be fast polymerized and cured by irradiation with various active energy rays and which gives a cured product with high accuracy by stereolithography, with little deformation such as warpage or swelling during molding, and to provide a strong and robust three-dimensional molded object.SOLUTION: The active energy ray-polymerizable resin composition for stereolithography comprises an α,β-unsaturated double bond group-containing compound (A) having at lest two aromatic rings in the molecule, an α,β-unsaturated double bond group-containing compound (B) having a cyclic structure (ca) including a nitrogen atom, and a photopolymerization initiator (C).SELECTED DRAWING: None
