<p>A multi-layer coating system comprising a hydroxyl-functional polyurethane dispersion is provided. The hydroxyl-functional polyurethane comprises the reaction product of a pre-polymer intermediate formed from the reaction of an isocyanate with an active hydrogen containing compound, such as a polyester polyol, with a compound having at least two amine groups and one hydroxyl group, such as a diamino alcohol. In addition, a waterborne basecoat composition is provided having improved rheology and pattern control. Such a waterborne basecoat composition comprises a hydroxyl-functional polyurethane dispersion, an acrylic emulsion resin, a water-reducible polyester resin, and a cellulose ester.</p> |
