    • 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 C.sub.3 -C.sub.5 -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.
    • 本发明涉及由通常的漆助剂和空气交联粘合剂组成的空气交联,着色或非着色涂料,其通过共聚合反应形成二羧酸半酯反应,所述共聚物由共聚单元 至少一个携带α,β-单烯属不饱和C3-C5-羧酸的至少一个1,2-环氧基或羟基的至少一个酯和至少一种与至少一种干燥脂肪酸不同的乙烯基或亚乙烯基单体 和任选地与至少一种环状二羧酸酐,其特征在于,所述涂层剂基于所述空气交联粘合剂,含有0.2至2重量%的至少一种α-二羰基化合物作为附加漆。
