ABSTRACT:
A composition comprising an aqueous-based solvent and a water-soluble or water-dispersible polymer that is characterized by having a backbone with at least one pendant weak acid group and at least one pendant strong cationic group associated with a bicarbonate counterion is described. A water-resistant, fast dry-to-the-touch coating that does not release noxious gases can be prepared by applying the composition to a substrate. The coating can be designed to be either permanent, or removable by the addition of mild acids such as aqueous solutions of vinegar or citric acid.
