摘要： The invention provides coating compositions comprising at least one compound (A) containing hydroxyl groups, at least one compound (B) containing isocyanate groups, at least 5.0% by weight, based on the nonvolatile constituents of the coating composition, of at least one amino resin (C), wherein the coating composition comprises at least one unsaturated, cyclic, sterically hindered amine (D) and the coating composition contains less than 2.5 mol % of hydrolyzable silane groups, based on the sum of hydroxyl groups, isocyanate groups, and hydrolyzable silane groups. The invention additionally relates to multistage coating processes using these coating compositions and also to the use of the coating compositions as clearcoat material and to the use of the coating process for automotive OEM finishing and automotive refinish.
