US 11,739,175 B2 · Curable resin composition and cured material

Abstract

An object of the present invention is to provide a curable resin composition in which the refractive index of a cured material is low and the adhesive strength to a member is excellent. There is provided a curable resin composition including: (A) component: an oligomer containing a (meth)acryloyl group and a fluorine atom in a molecule; (B) component: polyfunctional (meth)acrylate not containing a fluorine atom in a molecule; (C) component: a compound, not containing a fluorine atom in a molecule, of at least one selected from the group consisting of monofunctional (meth)acrylate containing a hydroxyl group, monofunctional (meth)acrylate containing an alicyclic ring, monofunctional (meth)acrylate containing an aromatic ring, (meth)acrylamide, and (meth)acrylic acid; and (D) component: a radical initiator, wherein a content of the (B) component is 0.1 parts by mass or more and 7.8 parts by mass or less relative to 100 parts by mass of the (A) component.
