Abstract
(EN)
The present invention provides a resin composition for optical shaping, particularly into an orthodontic mouthpiece or a denture base material, the resin composition having low viscosity and being easily shaped when shaped by optical shaping, and the resin composition enabling a shaped article having excellent toughness and water resistance to be obtained. The present invention relates to a resin composition for optical shaping, the resin composition containing a urethane (meth)acrylic compound (A) and a photopolymerization initiator (B), the urethane (meth)acrylic compound (A) being a (meth)acrylate containing a urethane bond and at least one type of polyol portion selected from the group consisting of polyesters, polycarbonates, polyurethanes, and polyethers having, in each molecule thereof, a structure derived from C4-18 aliphatic chain diol units (a) having a branched structure.
