An anti-glare hard coat film having a hard coat layer containing (A) at least one type of polyfunctional (meth)acrylate having at least three (meth)acryloyl groups per molecule and (B) at least one type of thermoplastic resin on a base film, wherein the anti-glare hard coat film is characterized in that, in the hard coat layer, the mass ratio of the total amount of component A:total amount of component (B) is 100:1-100:10, and the difference in the solubility parameter between the at least one type of polyfunctional (meth)acrylate and the at least one type of thermoplastic resin is 2-4. L'invention concerne un film de revêtement dur antireflet ayant une couche de revêtement dur contenant (A) au moins un type de (méth)acrylate polyfonctionnel ayant au moins trois groupes (méth)acryloyle par molécule et (B) au moins un type de résine thermoplastique sur un film de base, le film de revêtement dur antireflet étant caractérisé en ce que, dans la couche de revêtement dur, le rapport massique quantité totale de composant (A):quantité totale de composant (B) est de 100:1 à 100:10 et la différence de paramètre de solubilité entre ledit ou lesdits types de (méth)acrylate polyfonctionnel et ledit ou lesdits types de résine thermoplastique est de 2 à 4. 基材フィルム上に、（Ａ）少なくとも１種の、分子内に少なくとも３個以上の（メタ）アクリロイル基を有する多官能（メタ）アクリレート及び（Ｂ）少なくとも１種の熱可塑性樹脂を含むハードコート層を有する防眩性ハードコートフィルムであって、　当該ハードコート層において、Ａ成分の総量：Ｂ成分の総量の質量比は１００：１～１００：１０であり、　前記少なくとも１種の多官能（メタ）アクリレートと前記少なくとも１種の熱可塑性樹脂との間の溶解度パラメータの差が２～４である　ことを特徴とする防眩性ハードコートフィルム。
