| abstract |
The invention relates to a multicoat paint system comprising, lying above one another in this order,n (1) at least one first basecoat comprising basecoat material (A), (2) preferably a second, color and/or effect basecoat comprising basecoat material (B), and (3) at least one transparent coating comprising clearcoat material (C),n nwherein the basecoat material (A) which forms the first basecoat comprises at least one binder (a.1), at least one color and/or effect pigment (a.2), and a corrosion-inhibiting component (a.3) with a parent structure (GK 1 ), selected from the group of low molecular mass alkyl, aryl, aralkyl, and cycloalkyl radicals and/or heterocyclic radicals, which carries at least one phosphoric acid group as ligand (L 1 ), and/or at least one corrosion-inhibiting component with a parent structure (GK 2 ), selected from the group of alkyl, aryl, aralkyl, and cycloalkyl radicals, heterocyclic radicals and/or polymers, which carries at least one phosphonic acid group as ligand (L 2 ). |
