Excellent release surfaces are formed by curing a composition which is a dispersion of a reactive silicone present in an amount of from 1 to 30% by weight of the composition as a discontinuous phase in a continuous phase of a reactive resin comprising a reactive oligomer and optionally a reactive monomer. The product has a silicone release surface with silicone anchored in the coating. The surface is for releasable contact with a pressure-sensitive adhesive. Heat, electron beam and/or ultraviolet radiation may be used to achieve cure.
