Zusammenfassung: | The invention relates to a self-cross-linking, thermosetting, aqueous lacquer coating material, which comprises synthetic resins having a mean molecular weight (Mn) of about 500 to 15,000 and containing primary and/or secondary-and if appropriate also tertiary-amino groups as well as terminal esterified carboxyl groups, having an amine number of about 20 to 180 and an ester number of about 20 to 350, and which becomes dilutable with water through protonization with acids. The invention moreover concerns the utilization of this lacquer coating material for the purposes of cathodic deposition upon electrically conducting surfaces. |
