PROBLEM TO BE SOLVED: To provide a curable composition which is curable in the state of hardly generating a surface non-polymerized layer even when not using an oxygen blocking material in an environment where oxygen is present.SOLUTION: When a silicate mineral having a board-like shape is dispersed into a curable composition and cured, the formation of a layer with a non-polymerized surface can be suppressed. Namely, this dental curable composition is provided, which contains (A) a radically polymerizable monomer, (B) a 0.1-10 pts.mass silicate mineral having a board-like shape with respect to (A) the 100 pts.mass radically polymerizable monomer, and (C) an effective amount of radical polymerization initiator.COPYRIGHT: (C)2013,JPO&INPIT【課題】酸素の存在する環境下で、酸素遮断材を用いなくても、表面未重合層をほとんど形成させずに硬化させることのできる硬化性組成物を提供する。【解決手段】硬化性組成物中に板状の形状を有するケイ酸塩鉱物を分散させて硬化させると、表面未重合層の形成が抑制できる。即ち、(A)ラジカル重合性単量体と、(A)ラジカル重合性単量体100質量部に対し、0.1~10質量部の(B)板状型ケイ酸塩鉱物と、有効量の(C)ラジカル重合開始剤と、を含んでなることを特徴とする歯科用硬化性組成物が提供される。【選択図】なし
