<P>PROBLEM TO BE SOLVED: To provide a curable silicone composition for forming a highly transparent cured silicone material having flexing resistance, whose transparency dose not change with temperature. <P>SOLUTION: The curable silicone composition includes: (A)(A-1) a dialkylpolysiloxane having at least two alkenyl groups in one molecule and having viscosity in the range of 1,000-50,000 mPa s, and (A-2) an alkenyl-containing organopolysiloxane in a resin form consisting of SiO<SB>4/2</SB>unit, R<SP>1</SP><SB>2</SB>R<SP>2</SP>SiO<SB>1/2</SB>unit and R<SP>1</SP><SB>3</SB>SiO<SB>1/2</SB>unit, wherein R<SP>1</SP>is an alkyl group and R<SP>2</SP>is an alkenyl group and containing 0.5 to less than 3.5 mass% of alkenyl group; (B) an organopolysiloxane having at least 3 hydrogen atoms bonded to silicon atom in one molecule; and (C) a catalyst for hydrosilylation reaction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
