Abstract
The present invention is directed to a coating composition comprising a pigment, a water-dispersible urethane resin, and a solvent effective amount of a water-soluble solvent. The water-dispersible urethane resin exists as a colloidal dispersion in water but when mixed with a water-soluble solvent swells to provide a dispersion having a viscosity sufficiently high in the solvent so as to maintain the pigment in suspension in the solvent for a time sufficient to apply the coating composition. The present invention is also directed to a method for coating a substrate with the novel coating composition and to a coated substrate prepared by the novel method.
