Beschreibung
Zusammenfassung:	A high solids coating composition suitable for use, for example, as a high performance automotive coating is provided, which comprises (1) polyurethane polyol which are the reaction products of a symmetric 1,3-diol component and an isocyanate component, and (2) an hydroxyl group-reactive crosslinking agent. When formulated as a one-pack coating, preferably with an amino- plast crosslinking agent, these coating compositions possess a number of desirable properties including excellent acid etch resistance.
