Abstract

A water-dilutable lacquer based on an alkyd or acrylate resin containing carboxyl groups, which have been neutralized with an amine containing at least one 2,3-dihydroxy propyl group per amine nitrogen. The lacquers according to the invention are particularly suitable for use in the production of baked coatings on thermostable substrates, metal sheets, or shaped metal parts.
