PROBLEM TO BE SOLVED: To provide a curable composition capable of simultaneously satisfying surface hardness, scratch resistance, flexibility and curling property of a cured film obtained even with a low dose of ultraviolet irradiation, preferably an active energy ray-curable composition.SOLUTION: There is provided a curable composition which comprises the following (a) component and (B) component as essential components and contains 55 to 90 wt.% of (a) component and 10 to 45 wt.% of (B) component based on the total amount of (A) component and (B) component. (A) component: a mixture of an urethane (meth)acrylate (a1) obtained by addition reaction of pentaerythritol di- and/or tri(meth)acrylate and a polyisocyanate and pentaerythritol tetra(meth)acrylate (a2), (B) component: a poly(meth)acrylate mixture having a hydroxyl value of 10 to 50 mgKOH/g, which is a (meth)acrylate derived from mol 4 to 6 mol adduct of ethylene oxide of a tetrahydric or higher aliphatic polyhydric alcohol.SELECTED DRAWING: None |
