ABSTRACT:
A pressure sensitive adhesive film comprising a substrate film and a pressure sensitive adhesive layer formed on a surface of the substrate film, said pressure sensitive adhesive layer being prepared from (A) a silicone composition comprising a diorganopolysiloxane having at least two alkenyl groups per molecule and (C) a polyorganosiloxane having an SiH bond, characterized in that the alkenyl groups are contained in an amount of from 0.0007 to 0.05 mole per 100 g of the diorganopolysiloxane (A) and that the polyorganosiloxane (C) is contained 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.
