Abstract
An improvement in a method for coating an electrically conductive article by electrodeposition, wherein the article, as the cathode, is immersed in an aqueous bath containing a basic resin, at least partially neutralized with an acid compound, and a particulate synthetic resin, is provided. The improvement is the conducting of the electrodeposition continuously while adding a replenishing supply liquid to the aqueous bath to maintain a constant bath composition. The composition of the replenishing supply liquid is such that (a) the proportion of water is smaller than in the initial aqueous bath, (b) the proportion of the basic resin to the acid compound is larger than employed in the initial partial neutralization, and (c) the particulate synthetic resin is also present.
