Abstract: Polyvinyl alcohol based release coating compositions for strippable substrates which are in contact with pressure sensitive adhesives are disclosed. Substrates coated with the release compositions are easily peeled from pressure sensitive adhesive coated substrates without substantially adversely affecting the adhesive character of the adhesive coated substrate. The release coating composition comprises polyvinyl alcohol, a migratable release promoting agent, a water soluble salt of a coordinating metal and a water soluble boron compound in an aqueous solution. In addition to composites comprising release coated substrates affixed to adhesive coated substrates, the release compositions can be applied to the backing of a pressure sensitive adhesive tape to permit facile uncoiling of the rolled tape product.
