Abstract
The present invention provides a resin composition for stereolithographic modeling emitting a weak odor, having desirable shape accuracy, and made into a cured product having desirable strength, toughness, and color tone when used for stereolithographic modeling. The present invention relates to a resin composition for stereolithographic modeling, comprising: a polymerizable monomer (A); a photopolymerization initiator (B), and an organic peroxide (C), wherein the polymerizable monomer (A) comprises a (meth)acrylic acid ester compound (A-1) having a viscosity of 1,000 mPa·s or less and a normal boiling point of 270° C. or more and/or a (meth)acrylamide compound (A-2) having a viscosity of 1,000 mPa·s or less and a normal boiling point of 200° C. or more, and the photopolymerization initiator (B) is at least one selected from a (bis)acylphosphine oxide, an α-hydroxyketone compound, an α-aminoketone compound, a benzoin alkyl ether compound, a thioxanthone, a ketal, an α-diketone, and an anthraquinone.
