<p>The invention relates to an aerially-crosslinking, pigmented or non-pigmented coating agent consisting of conventional lacquer auxiliaries and an aerially-crosslinking binder which has been reacted to form a dicarboxylic acid semi-ester by the reaction of a copolymer consisting of copolymerized units of at least one ester carrying at least one 1,2-epoxide group or hydroxyl group of an alpha , beta -monoolefinically unsaturated C3-C5-carboxylic acid and at least one vinyl or vinylidene monomer which is different therefrom with at least one drying fatty acid and optionally with at least one cyclic dicarboxylic acid anhydride, characterized in that the coating agent contains as an additional lacquer auxiliary from 0.2 to 2% by weight of at least one alpha -dicarbonyl compound, based on the aerially-crosslinking binder.</p> |
