ABSTRACT COATING PROCESS A process of coating with film-forming material an article which is made a cathode in an electrical circuit and is immersed in either an aqueous dispersion of a deriv- ative of the film-forming material comprising a stabilising cationic group hydrolysable at the cathode or an aqueous dispersion of the film-forming material stabilised by assoc- iation with a distinct surfactant comprising a cationic group hydrolysable at the cathode, to yield the film-forming material as a coating on the cathode when electric current is passed between the cathode and a counter-electrode. Also suitable coating compositions in which the film-forming material is primarily stabilised by ionic groups hydrolysable at the cathode.
