Реферат: The present invention is directed to non-aqueous, curable film-forming compositions comprising: a) an anhydride functional compound; b) at least one of: (i) a hydroxyl functional compound having at least two hydroxyl functional groups and (ii) a carbodiimide functional compound; and c) hydrolyzable functional groups. After application of the curable film-forming composition to a substrate to form a coated substrate, and upon subjecting the coated substrate to curing conditions, the curable film-forming composition undergoes multiple cure reactions. The present invention is further directed to methods of preparing coated substrates with these compositions.
