  The present invention provides a resin composition for optical shaping that emits a weaker odor, enables easy fabrication of an object by virtue of its low viscosity, and can be made into a fabricated product having desirable toughness and water resistance when used for stereolithographic fabrication (particularly by vat stereolithography) and that is particularly suited for dental occlusal splints, mouth guards, and denture base materials. The present invention relates to a resin composition for optical shaping comprising: an α,β-unsaturated double bond group-containing compound (A) having a ring structure (a) containing a nitrogen atom; a (meth)acrylic acid ester compound (B) having a boiling point of 280°C or more at normal pressure, having a carbocyclic group, and having no nitrogen-containing heterocyclic group; a photopolymerization initiator (C); and optionally, a polyfunctional polymerizable monomer (E) having a molecular weight of 500 or less and not comprised in the α,β-unsaturated double bond group-containing compound (A) and the (meth)acrylic acid ester compound (B), wherein the content of the polyfunctional polymerizable monomer (E) having a molecular weight of 500 or less is 20 mass% or less relative to the total amount of polymerizable compounds comprised in the resin composition for optical shaping.

  本发明提供了一种用于光学整形的树脂组合物，该组合物散发的气味较弱，因其粘度低而易于制造物体，在用于立体光刻制造（特别是大桶立体光刻）时，可制成具有理想韧性和耐水性的制成品，特别适用于牙科咬合夹板、护齿板和义齿基底材料。本发明涉及一种用于光学塑形的树脂组合物，包括具有含氮原子的环结构 (a) 的含 α、β-不饱和双键基团的化合物 (A)；(甲基) 丙烯酸酯化合物 (B)，在常压下的沸点为 280°C 或更高，具有碳环基团，且不含含氮杂环基团；光聚合引发剂 (C)；以及可选的分子量为 500 或以下且不包含在含α，β-不饱和双键基团的化合物（A）和（甲基）丙烯酸酯化合物（B）中的多功能可聚合单体（E），其中分子量为 500 或以下的多功能可聚合单体（E）的含量占光学成型用树脂组合物中可聚合化合物总量的 20% 或以下。
