Abstract
The invention provides a method for improving the stability of the surface-releasing performance of a silicone-coated release paper so as to minimize the changes in the peeling resistance between the release paper and an adhesive surface bonded thereto even after lapse of time from preparation of the release paper to bonding of the adhesive surface or from bonding of the adhesive surface to peeling thereof. The method comprises providing an overcoating layer of an organotin compound such as dibutyl tin diacetate on the surface of a cured coating layer of an organopolysiloxane composition comprising a vinyl-containing organopolysiloxane, an organohydrogenpolysiloxane and a platinum catalyst to promote the addition reaction between the silicon-bonded vinyl groups and the silicon-bonded hydrogen atoms.
