<p>Disclosed is a curable composition that includes (A) a silane compound copolymer having specific repeating units, (B) an epoxy compound having an isocyanurate skeleton, (C) a curing agent that includes an alicyclic acid anhydride having a carboxyl group, and (D) a silane coupling agent having an acid anhydride structure. Also disclosed are a hardened material formed by hardening the composition and a method for using the aforementioned composition as an adhesive for an optical element fixing material and as a sealing material for an optical element fixing material. With the curable composition, a hardened material can be obtained that does not lose transparency with coloring and has excellent transparency over an extended period of time even when irradiated with high-energy light or when in a high temperature state, and that has high adhesive strength even at high temperatures. The curable composition can be used when forming an optical element fixing material, and in particular can be optimally used as an adhesive for an optical element fixing material and as a sealing material for an optical element fixing material.</p> |
