<p><P>PROBLEM TO BE SOLVED: To provide an adhesive film not entrapping bubbles at sticking and capable of being easily peeled off by hand although it is stuck without sliding by itself after it is stuck. <P>SOLUTION: The silicone adhesive composition contains (A) 100-80 pts.mass of diorganopolysiloxane having two or more of alkenyl group and phenyl group in one molecule in which 1.0-12 mol% of the phenyl group is contained in the entire organic group of the diorganopolysiloxane, 0.0005-0.05 mol of the alkenyl group is contained in 100 g of the diorganopolysiloxane and viscosity at 25°C is 100,000 mPa s or higher, (B) 0-20 pts.mass of organopolysiloxane containing a R<SP>1</SP><SB>3</SB>SiO<SB>0.5</SB>unit and a SiO<SB>2</SB>unit and having a molar ratio of R<SP>1</SP><SB>3</SB>SiO<SB>0.5</SB>unit/SiO<SB>2</SB>unit of 0.6-1.7, (C) organohydrogenpolysiloxane containing three or more of SiH groups, (E) an addition reaction catalyst, and (F) an organic solvent. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
