A cathodic electrophoretic enamelling process is characterized in that the electrophoretic enamelling bath contains at least 7.5 wt. % of a polyoxyalkylene polyamine or a mixture of several polyoxyalkylene polyamines of differing chemical structures, the percentage by weight being expressed with respect to the total binder content in the electrophoretic enamelling bath.
