PROBLEM TO BE SOLVED: To provide an active energy-curable composition for optical components, whose cured product is excellent in terms of warpage, recoverability from scratches, adhesion with plastic base materials, and transparency.SOLUTION: An active energy curable composition for optical components contains; an urethane (meth)acrylate oligomer (A); a bi- or multi-functional polyoxyalkylene polyol (meth)acrylate (B) containing no aromatic ring; a mono-functional (meth)acrylate (F) having a solubility parameter of 8-11 (cal/cm3)1/2 and a homopolymer with a glass transition temperature of -80 to 0°C; and a photopolymerization initiator (D). |
