METHOD OF COATING THE ELECTRICALLY CONDUCTIVE SUBSTRATE BY THE FILMMAKING MATERIAL

摘要

A coating process in which an article to be coated is immersed as an anode in a dispersion of a film-forming material stabilized by non-ionic stabilization and an electric current is passed between the anode and another electrode immersed in the dispersion. The dispersion is destabilized in the region of and is deposited on the anode by interaction between a moiety providing the non-ionic stabilization (e.g. of polyethylene glycol) and a further interactive moiety (e.g. carboxyl groups present in polymethacrylic acid) present in the dispersion. Suitable coating compositions and coated articles are defined.
