Patent ID: 7674499

Claim:
“A process for coating an auto body or auto part which comprises applying a base coating of a pigmented coating composition to a substrate; applying a top-coating of a clear coating of the composition over the base coating; and curing the base coating and top-coating to form a base coat/clear coat finish on the substrate, wherein the improvement comprises using as the clear top-coating, a clear coat composition which comprises a binder consisting essentially of a. polyisocyanate crosslinking agent; b. an isocyanate-reactive component having at least one compound having the following formula (I): wherein X can be independently O or N; when X equals O, n equals 1 and when X equals N, n equals 2; wherein R 1 is selected from H, a C 1 to C 20 linear or branched alkyl group, a C 5 to C 16 cycloaliphatic group, a phenyl group, a C 6 to C 20 aryl group substituted with a C 1 to C 12 alkyl group; wherein m, on average, equals 1, 2 or 3, wherein R 2 comprises the hydrocarbon radical obtained by removing the amino and hydroxyl groups from an amino alcohol having the following formula (V) wherein k equals 0, 1 or 2 and, when k equals 1 or 2, the additional bridging CH 2 group(s) may be on the same or opposite side with respect to the first bridging CH 2 group; B equals (—(CH 2 ) t (CH)—(CH 2 ) s —) r , r=0 or 1, s+t=1 to 16, with the —(CH)— group connecting to the —(CH 2 ) q — group, in which B forms a ring in place of one of R 20 , R 21 or R 22 substituents; R 20 , R 21 or R 22 can be the same or different and are each independently H, a C 1 to C 20 linear or branched alkyl group; q is equal to 1, 2, 3, or 4; R 23 , R 24 , R 25 and R 26 can be the same or different and are each independently H, a C 1 to C 20 linear or branched alkyl group; with the provision that at least one group independently selected from R 23 , R 24 , R 25 and R 26 is a —OH group, or a C 1 to C 20 linear or branched alkyl group bearing a hydroxyl group, and wherein p, on average equals, 1, 2 or 3.”
