ABSTRACT:
A radiation-curable silicone release composition is described which comprises (A) from about 2% to about 7% by weight of an organopolysiloxane containing acryloxy groups, methacryloxy groups, or mixtures thereof; (B) from about 90% to about 98% by weight of at least one acrylated or methacrylated organic polyhydroxy compound or polyamino compound; and (C) from 0% to about 5% by weight of a photoinitiator. In a preferred embodiment, (B) comprises a mixture of (i) at least one acrylated or methacrylated organic polyhydroxy compound and (ii) at least one acrylated or methacrylated polyamino compound. A method of producing silicone release-coated substrates, the release-coated articles thus produced and multilayer articles or constructions incorporating a silicone-release layer also are described. The release coated papers and the constructions embodying such release coated papers of the invention exhibit improved and desirable dimensional stability and remain flat under a variety of service conditions.
