Abstract
A curable silicone resin composition is provided which is useful as a material for optical devices or parts, insulation material for electronic devices or parts, or coating material, and which produces a cured product having high hardness and strength and further having good optical transmission in the short wavelength region. The composition includes (A) an aromatic hydrocarbon compound having at least two hydrogen atoms bonded to silicon atoms with the silicon atoms being bonded to the hydrocarbon skeleton of the aromatic hydrocarbon compound, (B) a cyclic siloxane compound having at least two silicon atom-bonded alkenyl groups, and (C) a hydrosilylation reaction catalyst, or (D) an aromatic hydrocarbon compound having at least two alkenyl groups bonded to silicon atoms with the silicon atoms being bonded to the hydrocarbon skeleton of the aromatic hydrocarbon compound, (E) a cyclic siloxane compound having at least two silicon atom-bonded hydrogen atoms, and (C) a hydrosilylation reaction catalyst.
