1-13. (canceled)
A two-component polyurethane-based coating system which consists essentially of
- (a) optionally hydrophilicized polyisocyanate,
- (b) optionally hydrophilicized compounds with isocyanate-reactive groups, in water and optionally in the presence of organic solvents or solvent mixtures,
- (c) alkali metal salts of phosphomolybdic acid, and
- (d) optionally other additives and auxiliary substances, the amount of (a)+(b) being 20 to 99.9999 parts by weight, the amount of (c) being 0.0001 to 5 parts by weight and the amount of (d) being 0 to 75 parts by weight, and the sum of the parts by weight being 100.
