Abstract
This invention relates to a curable release composition, comprising:(A) a compound represented by the formula wherein: n is a number in the range of about 1 to about 60; and T is  (B) a curable organopolysiloxane. This invention also relates to a method of making a release coated substrate comprising coating a substrate with the foregoing release composition and curing the coated composition. This invention relates to a release coated article comprising a substrate which has been coated with the foregoing release composition. The invention also relates to a multilayered article comprising a first substrate, a second substrate, a layer of the foregoing release composition which has been cured, and a layer of a pressure sensitive adhesive wherein the release layer is positioned between the first substrate and the layer of pressure-sensitive adhesive and is preferentially adherent to the first substrate, and the pressure-sensitive adhesive layer is positioned between the release layer and the second substrate and is preferentially adherent to the second substrate.
