Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a thermosetting acrylic resin composition good in curability and capable of achieving both of transparent feeling and productivity of a thermosetting acrylic resin composition after heating and pressing molding at good balance.SOLUTION: There is provided a thermosetting acrylic resin composition containing at least polymethyl methacrylate (A) and a reactive monomer and containing first reactive monomer having the melting point lower than molding temperature (B) and a second reactive monomer having the melting point higher than the molding temperature (C) as the reactive monomer.SELECTED DRAWING: None 【課題】硬化性が良好であって、かつ加熱加圧成形後の熱硬化型アクリル樹脂成形品の透明感と生産性とをバランスよく両立させることができる熱硬化型アクリル樹脂組成物を提供すること。【解決手段】少なくともポリメタクリル酸メチル（Ａ）と反応性モノマーを含有する熱硬化型アクリル樹脂組成物であって、反応性モノマーとして、沸点が成形温度よりも低い第１の反応性モノマー（Ｂ）と、沸点が成形温度よりも高い第２の反応性モノマー（Ｃ）とを含む。【選択図】なし
