Abstract
Waterborne coating compositions comprising polymeric film-forming resins and about 0.1 to 5 percent by weight based on weight of resin solids of an oligomer containing from about two to four urethane, urea, or amide moieties per molecule and two or more moieties selected from the group consisting of hydroxyl and tertiary amine. The oligomer improves the smoothness of the resulting coating.
