Abstract
Provided is a curable silicone resin composition including (A) a siloxane-based compound containing at least 2 addition reactive carbon-carbon double bonds within each molecule, (B) a siloxane-based compound containing at least 2 hydrogen atoms bonded to silicon atoms within each molecule, (C) a hydrosilylation reaction catalyst, (D) a phenol-based antioxidant, and (E) a hindered amine compound. Also provided are an optical semiconductor sealing material including such a composition, and an optical semiconductor device that has been sealed with such a composition. The curable silicone composition generates a cured product with high hardness and strength, excellent transparency, and excellent light transmittance and photostability particularly in the short wavelength region.
