The present invention is concerned with a coating composition which contains a resin and fine particles of an electrically conductive substance and/or an electrically semiconductive substance, a coating film to be formed therefrom on a work article surface exhibiting a varistor property represented by the equation (1): I = (V/V1)<n> (1) wherein I is a current density (mA/cm2); V1 is a voltage at which a current of 1 mA begins to flow when a voltage applied to the coating film is increased; V is an applied voltage; and n is an exponent showing the non-linearity between I and V and is 1.5 or more. Further, the present invention is concerned with a process for production of a coated metal article, which comprises applying the above-described coating composition in a dry film thickness of from 0.5 to 20 microns on a metal plate and/or a metal formed article with or without having been subjected to a surface treatment and then drying or baking at a temperature of from room temperature to 300 DEG C. Still further, the present invention is concerned with a method for further subjecting the formed coating film to electrodeposition coating. |
