Claim:
A method of crosslinking a coating composition, comprising using a compound (V) as a crosslinking agent in a curable coating composition, the compound (V) being the reaction product of at least one isocyanate compound (A) having an average NCO functionality of 2.0 to 6.0, with at least one compound of the general formula (I) where m is 2, 3 or 4; and R 1 , R 2 , and R 3 , independently of one another, are each H, unsubstituted or at least monosubstituted alkyl or unsubstituted or at least monosubstituted heteroalkyl, and from between 0.1% and 20% by weight, based on the nonvolatile constituents of the coating composition, of an amine-blocked phosphoric acid as a crosslinking catalyst; wherein from 0.1 to 99 mol % of the isocyanate groups originally present in the isocyanate compound (A) have been reacted with the at least one compound of the general formula (I).
