An aqueous coating composition is provided which includes crosslinkable film-forming resin and about 0.01 to about 25 weight percent on a basis of total resin solids of an amphiphilic adjuvant having an acid value of less than 30, a water-soluble polar end including at least one terminal hydroxyl group and a water-insoluble hydrocarbon end including at least seven contiguous carbon atoms. The coating composition is useful as a monocoat or primer, basecoat or clearcoat in a multi-component composite coating composition for automotive applications.

Multi-component composite coating composition and coated substrate

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.

Aqueous coating compositions, coated substrate and method related thereto

A coated substrate is provided which includes an outer coating formed from a film-forming composition which includes a crosslinkable, non-gelled acrylic polymer and a crosslinking material capable of reacting with the acrylic polymer to form a crosslinked outer coating. The acrylic polymer is the reaction product of a polyoxyalkylene acrylate monomer comprising a terminal alkoxy group containing about 1 to about 6 carbon atoms and a copolymerizable ethylenically unsaturated monomer different from the polyoxyalkylene acrylate monomer. A multi-component composite coating composition is also provided.
