Zusammenfassung:PROBLEM TO BE SOLVED: To provide a protective film for a touch panel, which is improved in both of weather resistance and contamination-prevention durability.SOLUTION: The protective film for a touch panel is to be mounted on a touch surface of a touch panel, and includes a UV-cured resin layer formed by curing a UV-curable resin composition containing a UV absorbent on a base film. After a surface of the UV-cured resin layer is subjected to a steel wool abrasion test described below, the surface of the UV-cured 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 steel wool to reciprocate on the surface of the UV-cured resin layer under the conditions of 250 g/cmload, 60 mm/sec traveling speed, 120 mm reciprocation distance, and 1000 times of reciprocation. 【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】タッチパネルのタッチ面に装着されるタッチパネル用保護フィルムであって、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せしめた紫外線硬化性樹脂層を備え、前記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度以上であることを特徴とする、タッチパネル用保護フィルム。(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
