Abstract:
A process for coating an electrically conductive substrate comprising immersing said substrate in a water-based electrophoretic coating bath containing at least one cathodically depositable synthetic resin and a polyalkylene oxide compound whose oxyalkyl groups contain 2 to 4 carbon atoms and the terminal OH groups are esterified with a carboxylic acid or etherified with an allyl or methyl aryl group, connecting said substrate as the cathode, depositing a film of said resin on said substrate by application of direct current, removing the substrate from said electrophoretic coating bath and stoving the deposited film, wherein said polyalkylene oxide compound has a solubility of more than 50 parts by weight in 100 parts by weight of water at 25.degree.
