Abstract
This invention relates release compositions that comprise a radiation curable polyorganosiloxane and cellulose fibers having an average fiber length of about 15 to about 100 microns and an average fiber thickness in the range of about 5 to about 40 microns. This invention also relates to a method of making a release coated substrate comprising coating a substrate with the foregoing release coating composition and curing the coating by exposing it to radiation. This invention relates to release coated articles made by the foregoing method. The invention also relates to multilayered articles comprising a first substrate, a second substrate, the foregoing release composition which has been cured by exposure to radiation, and a pressure sensitive adhesive, the release composition being adhered to the first substrate, the pressure sensitive adhesive being adhered to the second substrate, and the release composition and the pressure sensitive adhesive being adhered to each other.
