Abstract
A fast-setting coating material can be prepared by contacting a stable aqueous dispersion of a polymer that contains strong cationic groups and weak acid groups onto a substrate that is basic or rendered to be basic. Alternatively, the coating material can be prepared by contacting in either order or concurrently the surface of a substrate with two separate polymers, one of which contains strong cationic groups, and the other of which contains weak acid groups. In this case, the substrate need not be basic for the coating to quickly set.
