Abstract
A multi-component composite coating composition is provided which includes a basecoat deposited from an aqueous basecoat film-forming composition and a transparent topcoat applied over the basecoat, the transparent topcoat being deposited from a topcoat film-forming composition. The topcoat film-forming composition includes one or more crosslinkable film-forming resins and one or more amphiphilic adjuvants including: a water-soluble polar end having at least one terminal hydrophilic group selected from hydroxyl groups, carbamate groups, amide groups and urea groups; and a water-insoluble hydrocarbon end having at least six contiguous carbon atoms. The adjuvant has an acid value of less than 30 and is present in an amount ranging from about 0.01 to about 25 weight percent on a basis of total resin solids of the topcoat film-forming composition.
