CURABLE RESIN COMPOSITION AND CURED ARTICLE

摘要

The curable resin composition according to the present invention contains ladder silsesquioxane (A) and straight-chain polysiloxane (B) having a molecular weight of 100 to 9000, (A) and (B) being able to react with each other to form carbon-silica bonds by hydrosilylation, and a hydrosilylation catalyst (C). The curable resin composition may further contain an isocyanuric acid compound (D) that can form carbon-silica bonds by hydrosilylation by reacting with the ladder silsesquioxane (A) and/or straight-chain polysiloxane (B). Using the curable resin composition of the present invention, it is possible to obtain cured articles having high-temperature heat resistance, flexibility, transparency, resistance to heat-induced yellowing, resistance to light-induced yellowing, and the like.
