Zusammenfassung:PROBLEM TO BE SOLVED: To provide a protective film for a touch panel, which is improved in both of weather resistance and antifouling durability.SOLUTION: A protective film for a touch panel to be mounted on a touch surface of a touch panel includes an ultraviolet ray curable resin layer formed by curing an ultraviolet ray curable resin composition containing an ultraviolet ray absorbent on a base film. After subjecting a surface of the ultraviolet ray curable resin layer to a steel wool abrasion test described below, the surface of the ultraviolet ray curable resin layer shows a contact angle of 95 degrees or more with water. The steel wool abrasion test is carried out by using a steel wool #0000 and allowing the surface of the ultraviolet ray curable resin layer to be carried out with 1000 times of reciprocation under the conditions of 250 g/cmload, 60 mm/sec traveling speed and 120 mm reciprocation distance.SELECTED DRAWING: None 【課題】耐候性および防汚耐久性が共に改善されたタッチパネル用保護フィルムを提供する。【解決手段】タッチ面に装着されるタッチパネル用保護フィルムは、基材フィルム上に、紫外線吸収剤を含有する紫外線硬化性樹脂組成物を硬化させた紫外線硬化性樹脂層を備え、紫外線硬化性樹脂層表面の下記スチールウール摩耗性試験後の紫外線硬化性樹脂層表面における水接触角が95度以上である。(スチールウール摩耗性試験)紫外線硬化性樹脂層表面をスチールウール#0000を使用し、荷重250g/cm2、移動速度60mm/秒、往復移動距離120mmで1000往復させる。【選択図】なし
