Patent number: 7199194Abstract: This invention relates to rapid curing coating compositions that are particularly useful for automotive OEM and refinish applications. The coating composition includes a binder component that contains a novel highly branched copolyester polyol, and a crosslinking component that contains conventional crosslinking agents, such as polyisocyanate and melamine. This invention is also directed to a process for producing coatings from the rapid curing coating compositions. These compositions are especially useful in providing for mar resistant and flexible coatings.Type: GrantFiled: October 13, 2004Date of Patent: April 3, 2007Assignee: E. I. du Pont de Nemours and CompanyInventors: Robert John Barsotti, Carl Brent Douglas, Laura A. Lewin, Isao Nagato, Lech Wilczek
