AQUEOUS COATING COMPOSITIONS AND PROCESSES OF FORMING MULTI-COMPONENT COMPOSITE COATINGS ON A SUBSTRATE

The present invention relates to an aqueous coating composition comprising: (a) a film-forming resin selected from polyesters made from monomers comprising a polyetherpolyol and a polycarboxylic acid, the polyester bearing functional groups and having a Tg of less than -10°C measured according to ASTM D3418-15 (midpoint temperature, at a heating rate of 20°C/min); (b) a rheology modifier selected from inorganic and resinous rheology modifiers and combinations thereof; (c) one or more color-imparting pigments or effect pigments or combinations thereof; and (d) one or more cross-linking agents that are reactive with the functional groups of the film-forming resin according to a), wherein the coating composition exhibits a low shear viscosity of 0.5 to 40 Pas at 0.1 s -1 at 25°C measured according to ASTM 22196-15 Method B Spindle No X, a method for making said coating composition, a method for coating an automotive substrate utilizing said coating composition and a coated substrate comprising a base coat layer deposited from said coating composition.
