    摘要： Coating composition containing a resin and fine particles of an electrically semiconductive substance, whereby a coating film to be formed therefrom on a work article surface exhibits a varistor property represented by the following equation (1):I=(V/V.sub.1).sup.n (1)wherein I is a current density (mA/cm.sup.2); V.sub.1 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. Coating films formed from such coating composition exhibit excellent film forming and corrosion-resistant properties.

    摘要： A shaped or unshaped article of a non-ferrous metal sheet preferably aluminum having an organic, surface coating film containing conductive and/or semiconductive fine particles, preferably molybdenum dissulfide is integrally bonded with a shaped or unshaped article of a steel sheet having or not having an organic, surface coating film; and this integrated body is subjected simultaneously to electrodeposition coating.The non-ferrous metal sheet having an organic, surface coating film containing conductive and/or semiconductive, fine particles shows excellent electrodeposition coating characteristics which can be easily regulated. Hence, integral coating after bounding with a steel sheet gives the same degree of film thickness and surface smoothness on both of the non-ferrous metal and steel sheets. This method is particularly suitable for the coating of automobile bodies integrally composed of non-ferrous metal and steel sheets ensuring energy- and labor-saving and giving final products of uniform finish.

    摘要： A method of coating a metal article by forming a first electrodeposition coating layer having varistor properties on a metal article by an electrodeposition coating method by use of an electrodeposition coating film-forming composition containing from 7 to 50 parts by weight of an electrically semiconductive substance per 100 parts by weight of the solid content of the composition, and then forming a second electrodeposition coating layer on said first electrodeposition coating layer by an electrodeposition coating method by use of an anionic or cationic electrodeposition paint while applying a voltage exceeding the varistor voltage. The coating composition thus-produced has excellent varistor properties with superior corrosion resistance.
