Abstract: A water-in-water multicolor paint composition is provided that is based on carboxylated polymer which is film forming, water-dispersed, and cross-linkable and which is admixed with a film-forming, cross-linkable hydrophobic polyisocyanate. The paint has a disperse phase and a continuous phase. When applied as a coating and dried, the coating displays improved solvent (water and common organic liquids) resistance. Methods for preparing the paint are also provided.

Abstract: A multi-layer composite coating composition which comprises:(a) a first coat which is substantially free of isocyanate functionality and which comprises:(i) a film-forming composition capable of curing or drying; and(ii) a metal catalyst for the reaction of isocyanate groups and active hydrogen groups;(b) a second coat which is applied to the surface of the first coat prior to the complete curing of said first coat, wherein the second coat comprises:(i) an active hydrogen functional compound; and(ii) a polyisocyanate;whereby upon the application of said second coat onto the metal catalyst containing first coat, the reaction between the polyisocyanate and the active hydrogen functional compound of-the second coat is catalyzed.
