Abstract

A stoving lacquer contains (I) water, and (II) a mixture of (1) 65 to 75% by weight of at least one water-soluble salt of (a) at least one water-soluble volatile tertiary amine and (b) a copolymer comprising 82 to 88% isobutyl acrylate, 8 to 12% acrylic acid and 4 to 6% of N-(hydroxymethyl) methacrylamide, the sum of the percentages of these monomers being 100%, and (2) 35 to 25% of a water-soluble cocondensate of formaldehyde, a 1:3 to 1:6 by weight mixture of 2,2-bis-(p-hydroxyphenyl)-propane and phenol and, optionally, at least one alkanol having 1 to 4 carbon atoms. Suitable amines (a) are trimethylamine, tri-(b -hydroxyethyl) - amine, N,N - dimethyl - N - (b - hydroxypropyl) - amine, triethylamine and N,N - dimethyl - N - (b - hydroxyethyl) - amine. The lacquers may also contain organic solvents, e.g. monoalkyl ethers of diethylene and triethylene glycol, hexavalent chromium compounds, e.g. ammonium dichromate and pigments, e.g. TiO2. In examples, the lacquers are applied to sheet metal, exposed to air and stoved (see Division B2).ALSO:A stoving lacquer comprises (I) water and (II) a mixture of (1) 65 to 75% of at least one water soluble salt of (a) at least one water-soluble volatile tertiary amine and (b) a copolymer containing 82 to 88% isobutyl acrylate, 8 to 12% acrylic acid and 4 to 6% of N-(hydroxymethyl) methacrylamide and (2) 35 to 25% of a water soluble cocondensate of formaldehyde and a 1:3 to 1:6 mixture of 2, 2 bis - (p - hydroxyphenyl) - propane and phenol.

Suitable amines (a) are trimethylamine, tri-(b -hydroxyethyl)-amine, N, N-dimethyl-N-(b -hydroxyethyl)-amine, triethylamine and N, N-dimethyl-N- (b -hydroxypropyl)-amine. The lacquer may be applied to sheet metal e.g. by electrodeposition and stoved at 80 DEG to 180 DEG C.
