Patent ID: 8057909

Claim:
A method for protecting a surface of a flat panel display comprising a step of: applying a pressure sensitive adhesive film comprising a substrate film and a pressure sensitive adhesive layer formed on a surface of the substrate film, wherein said pressure sensitive adhesive layer is prepared from a silicone composition comprising: (A) a diorganopolysiloxane, having at least two alkenyl groups per molecule, which diorganopolysiloxane contains alkenyl groups in an amount of from 0.002 to 0.05 mole per 100 g of the diorganopolysiloxane (A); (B) a polyorganosiloxane comprising an R 1 3 SiO 0.5 unit and an SiO 2 unit in a molar ratio of the R 1 3 SiO 0.5 unit to the SiO 2 unit of from 0.6 to 1.7, wherein R 1 is a monovalent hydrocarbon group having 1 to 10 carbon atoms; and (C) a polyorganosiloxane having an SiH bond contained said composition in such an amount that a molar ratio of the SiH bond to the alkenyl group of the diorganopolysiloxane (A) ranges from 0.5 to 20, wherein in said composition a mass ratio of the diorganopolysiloxane (A) to the polyorganosiloxane (B) ranges from 95/5 to 55/45, and wherein the adhesive layer has an adhesion strength ranging from 0.01 to 0.5 N/10 mm measured according to the 180-degree peel test specified in the Japanese Industrial Standard Z 0237 on a film composed of a polyethylene terephthalate film having a thickness of 25 Î¼m and the adhesive layer having a thickness of 30 Î¼m provided on the polyethylene terephthalate film to a surface of a flat panel display.
