Zusammenfassung:To provide a reactive resin composition that can obtain a molding according to melt molding and can introduce a crosslinking structure by crosslinking treating the obtained molding, and a resin molding having excellent excoriation resistance and high surface hardness.SOLUTION: There is provided a reactive resin composition containing a (meth)acrylic polymer (A) and a polymerizable compound (B), in which the (meth)acrylic polymer (A) has a glass transition temperature of 55 to 70°C, the polymerizable compound (B) contains a polyfunctional acrylate, the reactive resin composition contains 85.0 to 99.5 mass% of the (meth)acrylic compound (A) and 0.5 to 15.0 mass% of the polymerizable compound (B) relative to a total amount of the reactive resin composition.SELECTED DRAWING: None 【課題】溶融成形により成形体を得ることが可能であり、得られた成形体に架橋処理を行うことで架橋構造を導入することが可能な反応性樹脂組成物を提供する。耐擦傷性に優れ、高い表面硬度を有する樹脂成形体を提供する。【解決手段】(メタ)アクリル系重合体(A)、重合性化合物(B)を含む反応性樹脂組成物であって、前記(メタ)アクリル系重合体(A)のガラス転移温度が55〜70℃、前記重合性化合物(B)が、多官能アクリレートを含み、前記反応性樹脂組成物が、前記反応性樹脂組成物の総質量に対して、(メタ)アクリル系重合体(A)85.0〜99.5質量%と重合性化合物(B)0.5〜15.0質量%を含む、反応性樹脂組成物。【選択図】 なし
