An active energy ray-curable composition having a tensile elastic modulus, a tensile fracture strength, and a tensile fracture elongation, capable of forming a cured product layer having excellent surface hardness and transparency, and having a low cure shrinkage ratio during polymerization. Get. A urethane (meth) acrylate (A) obtained by reacting (a1) a polycaprolactone polyol, (a2) a diisocyanate compound, and (a3) a hydroxyl group-containing (meth) acrylic acid ester, represented by the following general formula (I) ) Urethane di (meth) acrylate (B), [Chemical 1] (In the formula, R 1 represents a diisocyanate residue, R 2 represents an alkylene group, and R 3 represents a hydrogen atom or a methyl group.) And an active energy ray-curable composition containing (meth) acrylic acid ester (C) other than (A) and (B). [Selection figure] None |
