Abstract
A pressure sensitive adhesive film comprises a substrate film and a pressure sensitive adhesive (PSA) layer formed on a surface of the substrate film. The PSA layer is formed from a silicone composition comprising: a diorganopolysiloxane having at least two alkenyl groups in a molecule and having a viscosity at 25° C. of from 10,000 to 1,000,000 mPa·s; (B) a diorganopolysiloxane having at least one alkenyl group in a molecule, and being raw and rubber-like at 25° C. or having a viscosity at 25° C. of more than 1,000,000 mPa·s; (C) an organopolysiloxane resin represented by the following average unit formula: (RSiO)(SiO), wherein each Rrepresents a halogen-substituted or unsubstituted monovalent hydrocarbon group free from an alkenyl group and x is a number from 0.5 to 1.0; (D) an organohydrogenpolysiloxane having at least two silicon-bonded hydrogen atoms in a molecule; (E) silica fine powder; and (F) a hydrosilylation catalyst.
