Document Type and Number:

WIPO Patent Application WO/2016/199561

Kind Code:

A1

Abstract:

Provided are: an additive reaction-type silicone composition that is for release paper or for a release film, that is non-migratory, and that exhibits light releasability with respect to various adhesives, said silicone composition for release paper or for a release film making it possible to form a cured film that does not adversely affect residual adhesive strength or releasability; and a release paper or a release film obtained by applying the composition to a substrate and curing the result. In a silicone composition for release paper or a release film cured by additive reaction, an organopolysiloxane containing an alkenyl group having a terminal unsaturated bond is used as a base polymer, and a specific amount of an organopolysiloxane that has a lower molecular weight than the base polymer and that contains an alkenyl group having a terminal unsaturated bond is mixed with the base polymer.
