<p><P>PROBLEM TO BE SOLVED: To obtain a silicone-based pressure-sensitive adhesive for forming a pressure-sensitive adhesive layer having excellent removability after being exposed in a high temperature and an adhesive tape having excellent removability after being exposed in a high temperature. <P>SOLUTION: The silicone-based pressure-sensitive adhesive comprises at least (A) a mixture of (a) a crude rubber-like organopolysiloxane containing one or more alkenyl groups on the average in one molecule and (b) an organopolysiloxane resin substantially consisting of an R<SP>1</SP><SB>3</SB>SiO<SB>1/2</SB>unit and an SiO<SB>4/2</SB>unit or their partial condensation reaction product, (B) an organopolysiloxane containing two or more hydrogen atoms bonded to a silicon atom on the average in one molecule, (C) a phenol-based antioxidant and/or a phenol-modified organosiloxane, (D) an aromatic amine-based antioxidant and/or an aromatic amine-modified organosiloxane and (E) a platinum-based catalyst. The adhesive tape comprises a supporting film and a silicone-based pressure-sensitive adhesive layer that is formed on the film and is obtained by curing the silicone-based pressure-sensitive adhesive. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
