Abstract
A coating composition with a solids content of at least about 65% by weight comprises a polyanhydride having more than one non-cyclic anhydride moiety, a co-reactant resin such as a glycidyl (meth)acrylate-containing polymer and a latent catalyst wherein the equivalent ratio of epoxy to anhydride is from about 0.8:1 to 1.3:1.
