Patent ID: 7163984

Claim:
A curable waterborne coating composition consisting essentially of (A) an aqueous dispersion comprising an organic binder component (A1) comprising at least 5% by weight of (a) a reactive component which is substantially free of any heteroatoms and is not a crystalline solid at room temperature comprising (i) from 12 to 72 carbon atoms, and (ii) two or three functional groups, based on the total weight of organic binder component (A1), and (b) one or more film-forming components including at least one of polymers, oligomers, monomers, or mixtures thereof having at least one functional group and (B) at least one crosslinking component comprising a plurality of functional groups (iii) reactive with the functional groups of compound (b), wherein said functional groups react with functional groups on at least one of (a)(ii) or (b) and are selected such that reaction there between produces a thermally irreversible chemical linkage that is a urethane or ester linkage.
