Patent ID: 8440776

Claim:
A method of improving mold release of a silicone lens from a mold cavity upon injection molding a colorless and transparent silicone resin composition free of mold release agent for forming the silicone lens comprising subjecting a lens-forming silicone resin composition comprising (A) an organopolysiloxane containing at least two aliphatic unsaturated bonds in a molecule and having a viscosity of at least 100 mPa·s at 25° C., (B) an organohydrogenpolysiloxane having in a molecule at least four hydrogensiloxy structures of the following formula wherein R is a monovalent hydrocarbon group, and (C) a platinum group metal base catalyst, to injection mold in the mold cavity, and then to take out a molded product from the mold cavity, thereby obtaining a colorless and transparent silicone lens.
