摘要:
Provided is a material suitable for an optical element, which can be applied by inkjet, has an ultraviolet curable characteristic, and yields a cured product excellent in transparency and hardness and having a refractive index of more than 1.5. Specifically, an optical element excellent in transparency and hardness and having a refractive index of more than 1.5 is obtained by preparing a resin composition including at least: (A) 5 to 45 mass % of a vinyl group-containing copolymer obtained by copolymerization of a divinyl aromatic compound; (B) 55 to 94 mass % of a liquid photocurable polyfunctional (meth)acrylate having two or more (meth)acryloyl groups; (C) 0.97 to 20 mass % of a photopolymerization initiator; and (D) 0.03 to 1 mass % of a surfactant, and applying the resin composition onto a support substrate by inkjet, followed by photocuring.
