[과제] 우수한 소포성을 가지며, 또한 높은 내찰상성을 발현하는 하드코트층의 형성재료를 제공한다. [해결수단] (a)활성에너지선 경화성 다관능모노머 100질량부, (b)폴리(옥시퍼플루오로알킬렌)기를 포함하는 분자쇄의 양 말단에, 폴리(옥시알킬렌)기를 개재하거나 또는 폴리(옥시알킬렌)기 및 1개의 우레탄결합을 이 순으로 개재하여, 활성에너지선 중합성기를 갖는 퍼플루오로폴리에테르 0.1~10질량부, (c)활성에너지선에 의해 라디칼을 발생하는 중합개시제 1~20질량부, (d)폴리스티렌 환산으로 측정되는 중량평균분자량이 10,000~200,000이고, 또한 불소함유량이 31질량% 이상인 플루오로실리콘 화합물로 이루어지는 소포제 0.0001~0.004질량부, 및 (e)유기용매를 포함하는 경화성 조성물, 그리고 이 조성물로부터 얻어지는 경화막으로 이루어지는 하드코트층을 구비하는 하드코트필름. [Problem] To provide a material for forming a hard coating layer, which has excellent low-foaming properties, while enabling the achievement of high scratch resistance. [Solution] A curable composition which contains (a) 100 parts by mass of an active energy ray-curable polyfunctional monomer, (b) 0.1-10 parts by mass of a perfluoropolyether which has an active energy ray-polymerizable group at both ends of a molecular chain containing a poly(oxyperfluoroalkylene) group via a poly(oxyalkylene) group or via a poly(oxyalkylene) group and one urethane bond in this order, (c) 1-20 parts by mass of a polymerization initiator which generates radicals by means of an active energy ray, (d) 0.0001-0.004 part by mass of an antifoaming agent which is composed of a fluorosilicone compound that has a fluorine content of 31% by mass or more, while having a weight average molecular weight of 10,000 to 200,000 in terms of polystyrene, and (e) an organic solvent; and a hard coating film which comprises a hard coating layer that is composed of a cured film formed from this composition.
