Abstract:
A coating composition including an aqueous dispersion of a copolymerization product of a mixture of monomers including carbamate-functional and (meth)acrylic monomers, some having carboxylic acid-functionality. The monomer mixture is essentially free of hydroxyl monomer. The coating can be applied on a polycarbonate substrate. The coating composition may be a clearcoat coating composition, preferably an automotive clearcoat coating composition. The invention provides a method of producing such a coating and application on a substrate, particularly as a basecoat/clearcoat composite coating, with the coating composition of the invention preferably being at least the clearcoat of the composite coating. If the substrate is a polycarbonate, the clearcoat can be applied directly on the substrate without any primer or basecoat.
