Use of copolymers containing amino groups in aqueous, clear water-soluble preparation as a temporary coating in paint booths, obtained by copolymerization of a) 15 to 90 wt .-% of a nitrogen-free monomer or more with an olefinic double bond and b) 85 to 10% by weight of one or more linearly polymerizable monomers containing at least one tertiary amino function, diallylamine, 2-vinylpyridine and / or 4-vinylpyridine, the amino groups of the copolymers optionally being completely or partially neutralized or quaternized. |
