ABSTRACT:
Aqueous coating compositions are described characterized in that the resin binder comprises (a) from about 5 to 90 percent by weight of a water-soluble polyhydroxy component containing at least about 1 mole of amine oxide structure in 1000 grams of solids; and (b) from about 5 to 90 percent by weight of a polycarboxy component having an acid value of from about 30 to 280 mg KOH/g, the carboxy groups of which are partially or completely neutralized with a nitrogen base; components (a) and (b) forming a physical blend or a partial condensation product, the degree of said partial condensation not surpassing the solubility of the composition. Optionally, the coating composition can include from about 5 to 40 percent by weight of a polyvalent resin without polyelectrolyte character which will react with hydroxyl groups. Paint formulations of the coating compositions can be formulated with water constituting more than about 70 percent of the total solvent content. The coating formulations with the high water content have suitable viscosity characteristics and provide coatings having good durability, impact resistance, and corrosion resistance.
