    Abstract: A fast curing, high solids coating composition that is adapted for use as an automotive topcoat and which upon curing forms a hard, glossy, durable coating exhibiting excellent resistance to solvents and water. The coating composition contains greater than about 60 percent by weight of nonvolatile solids and, exclusive of pigments, solvents and other nonreactive components, consists essentially of:(A) a bifunctional copolymer bearing hydroxy functionality and pendant epoxy functionality, having a number average molecular weight (M.sub.n) of between about 1500 and about 10,000 and a glass transition temperature (Tg) of between about -25.degree. and about 70.degree.:(B) a reactive catalyst comprising at least one hydroxy functional organophosphate ester selected from certain mono-and diesters of phosphoric acid;(C) an amine-aldehyde crosslinking agent; and(D) optionally, a hydroxy functional additive. The hydroxy functional organophosphate ester is included in the composition in an amount sufficient to provide between about 0.67 and about 1.4 equivalents of acid functionality in copolymer (A), and the amino crosslinking agent is included in the composition in an amount sufficient to provide at least about 0.4 equivalents of nitrogen crosslinking functionality for each equivalent of hydroxy functionality included in the composition.

    Abstract: The present invention provides a coating composition which cures at low temperatures to form a cured film having high solvent resistance. The present invention provides a low-temperature-curable coating composition which comprises (A) a film-forming polymer having a hydrogen-donating functional group that has a heteroatom which bonds covalently to a hydrogen atom, (B) a film-forming polymer having a specific hydrogen-accepting functional group that has a heteroatom to which no hydrogen atom bonds covalently, and (C) a non-basic volatile solvent selected from the group consisting of a non-basic volatile solvent (C-1) having, in the molecule, both a heteroatom that bonds covalently to a hydrogen atom and a heteroatom that does not bond covalently to a hydrogen atom; a mixture of a non-basic volatile solvent (C-2) having, in the molecule, a heteroatom which bonds covalently to a hydrogen atom and a non-basic volatile solvent (C-3) having, in the molecule, a heteroatom to which no hydrogen atom bonds covalently; and combinations thereof.
