[과제] 연신성 및 우수한 내찰상성을 가지며, 또한 투명한 외관을 나타내는 하드코트층의 형성재료를 제공한다. [해결수단] (a)활성에너지선 경화성 락톤변성다관능모노머 100질량부, (b)폴리(옥시퍼플루오로알킬렌)기를 포함하는 분자쇄의 양 말단에, 우레탄결합을 개재하여, 활성에너지선 중합성기를 갖는 퍼플루오로폴리에테르(단, 상기 폴리(옥시퍼플루오로알킬렌)기와 상기 우레탄결합 사이에 폴리(옥시알킬렌)기를 갖는 퍼플루오로폴리에테르를 제외한다.) 0.1~10질량부, 및 (c)활성에너지선에 의해 라디칼을 발생하는 중합개시제 1~20질량부를 포함하는, 경화성 조성물, 및 이 조성물로부터 형성되는 하드코트층을 구비하는 하드코트필름. [Problem] To provide a material for forming a hard coating layer having extensibility and excellent scratch resistance and presenting a transparent appearance. [Solution] A curable composition containing (a) 100 mass parts of an active energy ray-curable lactone-modified polyfunctional monomer, (b) 0.1-10 mass parts of a perfluoropolyether having an active energy ray-curable group at both ends of a molecular chain containing a poly(oxyperfluoroalkylene) group via urethane bonds (however, excluding perfluoropolyether having a poly(oxyalkylene) group between the poly(oxyperfluoroalkylene) group and the urethane bond), and (c) 1-20 mass parts of a polymerization initiator that generates radicals by active energy rays, and a hard coating film provided with a hard coating layer formed from the composition.
