    • A curable composition and process of applying the composition and the resulting composite coatings provide improved resistance to acid etch and mar. The curable composition has (a) about 30 to 90 percent by weight, based on total weight of resin solids, of a film-forming composition selected from the group consisting of: (i) a polyepoxide and a polyacid cross-linking agent; (ii) an acrylosilane polymer, an acrylic polyol polymer, and optionally an alkylated melamine-formaldehyde cross-linking agent; and (iii) a polyisocyanate and a polymer having at least one group that is reactive with isocyanate; and (b) about 10 to 70 percent by weight, based on total weight of resin solids, of a tricarbamoyl triazine compound of the formula: C3N3(NHCOXR)3, wherein X is nitrogen, oxygen, sulfur, phosphorus, or carbon, and R is a lower alkyl group having 1 to 12 carbon atoms, or mixtures of lower alkyl groups. The process involves applying the curable coating as a monocoat on a cured primer surfacer coating on a substrate or as a clear coat on a curable base coat that are cured separately or conjointly. The composite coating includes the primer surfacer and monocoat on a substrate or the color-plus-clear coating on an electrodeposited coating layer or a primer surfacer coating layer.
