Patent ID: 8197905

Claim:
A process which comprises applying a solvent-based coating composition having a low content of volatile organic compounds of 2.1 lbs/gal and below on a substrate to obtain a clear coating layer of a multi-layer coating thereon, said solvent-based coating composition comprising a binder component and a crosslinking component, wherein the binder component comprises A) at least one hydroxy-functional polyether having at least two secondary hydroxyl groups per molecule, a number average molecular weight Mn in the range of 200 to 5,000 and a polydispersity of <2, wherein the polyether A) is obtained from Aa) at least one polyol having at least three hydroxyl groups and Ab) at least one monoglycidyl ester of a branched monocarboxylic acid, having 5 carbon atoms in the molecule, and wherein the crosslinking component comprises B) at least one cross-linking agent which is capable of entering into a cross-linking reaction with the hydroxyl groups of the hydroxy-functional polyether A), wherein the binder component consists of 80 to 100 percent by weight of the at least one hydroxy-functional polyether A) and 0 to 20 percent by weight of at least one additional hydroxyl-functional binder that is different from the hydroxyl-functional polyether A), and curing said multi-layer coating.
