Abstract
A releasing agent silicone composition which gives an improved cured film for rendering surfaces non-adherent having lasting releaseability, good slip factor, and stable peeling strength and rate of residual adhesive strength, even when the adhesive material is acrylic, employs a first organopolysiloxane having at least two silicon-bonded unsaturated groups, a second organopolysiloxane having at least two silicon-bonded hydrogen atoms, and a third organopolysiloxane having one end terminated by a Si--H bond.
