Abstract
Abstract An electrically conductive composition for electrodeposition coating comprises (A) a pigment and at least one cationic high molecular resin and (B) electrically conductive ultra-fine particles having an average particle diameter less than 0.8 mu , the amount of (A) being 96-50% by weight and the amount of (B) being 4-50% by weight of the total solid content of the composition.
