摘要
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.
