摘要：
Silicone resin compositions comprising (A) an organopolysiloxane containing at least two aliphatic unsaturated bonds and having a viscosity of 100-1,000,000 mPa·s at 25° C., (B) an organohydrogenpolysiloxane having at least three silicon-bonded hydrogen atoms (SiH groups) in the form of HR62SiO—, and (C) a platinum group metal base catalyst cure into colorless transparent parts which are useful lenses.
