ABSTRACT:
A baking lacquer based on acrylate polymers in organic solvents, optionally with coloring pigments and/or fillers is disclosed. The layer is characterized by a combination of two acrylate polymers A and B, wherein acrylate polymer A is a copolymer of copolymerizable ethylenically unsaturated compounds possessing free carboxyl groups originating from copolymerized alpha, beta-ethylenically unsaturated carboxylic acids, a proportion of the free carboxyl groups being esterified with a glycerol radical, which also contains other fatty acid radicals attached by ester bonds, so that 0.5-3 moles of free alpha, beta-ethylenically unsaturated carboxylic acid and 0.6 to 2 moles of alpha, beta-ethylenically unsaturated carboxylic acid esterified with the glycerol radical are employed per 1,000 g of acrylate polymer, and wherein acrylate polymer B is a polymer of an alpha, beta-ethylenically unsaturated carboxylic acid and, optionally, other, copolymerizable, ethylenically unsaturated compounds, in which the carboxyl groups are esterified with a radical which contains at least one epoxide group, the number of epoxide groups being so chosen as to give an epoxide equivalent weight of between 120 and 2,000.
