ABSTRACT:
A coating of a film-forming material is applied without electricity to a metal by immersing the metal in an aqueous dispersion which contains a film-forming material cationically dispersed in a cationic dispersion which contains a carboxylic acid radical capable of reacting with metal ions obtained by etching the metal to form a negatively charged complex in the dispersion.
