Abstract

In the present invention, compounding an addition-reaction-curable organopolysiloxane composition with a specific amount of an organopolysiloxane compound that has three or more (meth)acryl groups in the molecule and a weight-average molecular weight of 1,000 or greater yields an organopolysiloxane composition for use in a release paper or release film in which addition reactions can occur using a small amount of platinum family metal catalyst, cured films can be formed having a peeling strength approximating levels encountered in the past, and addition-reaction-prompted curing will proceed even on a base material containing a catalyst-poisoning component.
