12 Claims

1. A resin composition for stereolithographic modeling, comprising:

a polymerizable monomer;

a photopolymerization initiator; and

an organic peroxide,

wherein the polymerizable monomer comprises:

a (meth)acrylic acid ester compound 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 having a viscosity of 1,000 mPa·s or less and a normal boiling point of 200° C. or more, and

wherein

the (meth)acrylic acid ester compound comprises a monofunctional (meth)acrylic acid ester compound having an aromatic ring and/or a monofunctional (meth)acrylic acid ester compound having an alicyclic ring, and

the photopolymerization initiator is at least one selected from the group consisting of (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.
