| abstract |
The present invention relates to (A) a silane compound copolymer having a specific repeating unit, (B) an epoxy compound having an isocyanurate skeleton, (C) a curing agent containing an alicyclic acid anhydride having a carboxyl group, and (D) A curing composition containing a silane coupling agent having an anhydride structure, a cured product obtained by curing the composition, and a method of using the composition as an adhesive for optical device fixing material and a sealing material for optical device fixing material. According to the curable composition of the present invention, even when a high-energy light is irradiated or in a high-temperature state, there is no case where the transparency is lowered due to coloring, and it has excellent transparency for a long period of time, Cargo can be obtained. The curable composition of the present invention can be used for forming an optical element fixing material, and can be preferably used as an optical element fixing agent and an optical element fixing agent. |
