This invention relates to articles comprising a substrate bearing a coating formed from a blend of polymers. Many articles having the desired properties of durability, strength, optical clarity, can be adversely affected by the surfaces of those articles. It would be desirable to provide a coating material that could alter the surface of an otherwise useful article. This invention provides an article comprising a substrate bearing an optically clear, non-crosslinked coating formed from a blend comprising at least one polymer containing carbonylamido functional groups and at least one hydrophobic polymer substantially free of acidic functional groups. The coating is useful for promoting adhesion, increasing the hydrophilicity of the surface of the article, and increasing receptivity of the substrate for aqueous based inks.
