Abstract
(EN) Provided is a light release additive for release sheets, the additive being capable of achieving a desired light release force with a small addition thereof to an organopolysiloxane composition for release sheets and of providing an excellent release coating such that the released adhesive sheet has a high subsequent adhesion. This light release additive for release sheets comprises an acryl-silicone-based graft copolymer with a weight-average molecular weight of 1,000 to 100,000 obtained by radical polymerization of (A) an organopolysiloxane compound having an acrylic group and/or a methacrylic group and (B) a radical polymerizable monomer having one radical polymerizable group per molecule.
(FR) L'invention concerne un additif anti-adhésif léger pour feuilles anti-adhésives, l'additif permettant d'obtenir une faible force de décollement souhaitée à l'aide d'une petite addition de celui-ci à une composition d'organopolysiloxane pour feuilles anti-adhésives et de fournir un excellent revêtement anti-adhésif de sorte que la feuille adhésive décollée présente une adhérence ultérieure élevée. Ledit additif anti-adhésif léger pour feuilles anti-adhésives comprend un copolymère greffé à base d'acryl-silicone ayant une masse moléculaire moyenne en poids de 1000 à 100 000 obtenu par polymérisation radicalaire de (A) un composé organopolysiloxane comportant un groupe acrylique et/ou un groupe méthacrylique et de (B) un monomère polymérisable par voie radicalaire comportant un groupe polymérisable par voie radicalaire par molécule.
