SILICONE RESIN COMPOSITION, SILICONE RESIN USING THE SAME AND OPTICAL SEMICONDUCTOR SEALED-BODY

摘要

PROBLEM TO BE SOLVED: To provide a silicone resin composition excellent in productivity and capable of being converted into a silicon resin excellent in surface tackiness.

SOLUTION: This silicone resin composition includes: (A) a polysiloxane having at least two alkenyl groups bonded to a silicon atom; (B) a polysiloxane crosslinker having at least two hydrogen groups bonded to a silicon atom; (C) at least one organic metal compound selected from the group consisting of an organic zirconyl compound having an organic group of 3 or more carbon atoms, an organic zinc compound, an organic magnesium compound and an organic potassium compound, and there are provided also a silicone resin obtained by curing the silicone resin composition and an optical semiconductor element sealed-body in which an LED chip is sealed with the silicone resin.
