Title: Method of priming polyolefin articles for coating

Abstract: A method for providing a waterborne, inorganic barrier coating to a polyolefin substrate is described. The method involves applying a primer composition containing a vinyl polymer, wherein at least 75% of the polymer repeat units contain side groups having hydroxyl moieties, to the substrate. This primer coating facilitates the application and binding of the subsequently applied barrier coating composition to the substrate.
