Patent ID: 7871708

Claim:
A composite coated substrate comprising: (a) a substrate selected from the group consisting of metallic substrates, polymeric substrates and combinations thereof, wherein a surface of the substrate is essentially free of a primer coating; (b) a basecoat deposited upon the surface of the substrate, the basecoat being formed from a powder basecoating composition comprising: (i) at least one film-forming material comprising a thermosettable polyester and a curing agent; (ii) at least one reaction product of at least one cyclic carboxylic acid anhydride, at least one alkene and at least one reactant selected from the group consisting of primary amines, aliphatic polyamines, primary amino alcohols, alcohols, isocyanates and mixtures thereof, the copolymer having a number average molecular weight ranging from about 1,000 to about 20,000; and (iii) at least one flow control agent; and (c) a topcoat deposited from a liquid or powder slurry topcoating composition applied over the basecoat to provide a composite coated substrate.
