Process for coating articles by electrodeposition, compositions for use in the process and coated articles.

摘要

A coating process in which an article to be coated is immersed as an anode in a dispersion of a filmforming material stabilised by non-ionic stabilisation and an electric current is passed between the anode and another electrode immersed in the dispersion. The dispersion is destabilised in the region of and is deposited on the anode by interaction between a moiety providing the non-ionic stabilisation (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.
