    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 polyepoxide resin having a number average molecular weight (M.sub.n) of between about 140 and about 3,000;(B) a reactive catalyst comprising at least one hydroxy functional organophosphate ester selected from certain mono- and diesters of phosphoric acid;(C) an amino resin 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 for each equivalent of epoxy functionality in the polyepoxide resin and the amine-aldehyde 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: There is provided a coating composition with excellent storage stability, and with excellent mar resistance for obtained coating films. The coating composition comprises a hydroxyl group-containing resin (A), a curing agent (B) and a dispersion of acrylic resin-coated silica particles (C), the dispersion of acrylic resin-coated silica particles (C) being an acrylic resin-coated silica particle dispersion obtained by reacting silica particles with a polymerizable unsaturated group (c1) and a polymerizable unsaturated monomer (c2) in a mass ratio of (c1):(c2)=20:80 to 90:10, the polymerizable unsaturated monomer (c2) including a specific polymerizable unsaturated monomer (c2-1) as at least a portion of its components, and the molecular weight of the resin covering the silica particles being 400 to 6000.
