Abstract
A radiation-curable surface-releasing agent is proposed which is capable of giving surface releasability to a substrate surface by irradiation with electron beams or ultraviolet light exhibiting outstandingly low peeling resistance against peeling of pressure-sensitive adhesive tapes applied and bonded to the release-treated surface and very small migration of the releasing ingredient toward the adhesive surface. The surface-releasing agent is a composition comprising a linear diorganopolysiloxane having, only at one of the molecular chain ends, at least one (meth)acryloxy groups and a poly(meth)acrylate compound such as trimethylol propane tri(meth)acrylate, diethylene glycol di(meth)acrylate, pentaerithritol tri(meth)acrylate and the like.
