ABSTRACT:
This invention is directed to an article comprising a backing layer, at least one pressure sensitive adhesive layer, and an aqueous release coating layer, wherein the pressure sensitive adhesive layer is affixed to at least one side of the backing layer and the aqueous release coating layer comprises a polymer, preferably having acid functionality, and an aqueous solution or dispersion of an organic compound having at least one fatty acid ester and at least one quaternary amine, such as lecithin.
A method of making the release coated article is also disclosed.
The aqueous release coating layer which does not migrate into the pressure sensitive adhesive layer and interfere with the adhesive properties of the pressure sensitive adhesive permits the pressure sensitive adhesive layer to be easily separated from the backing layer.
