Abstract: The present invention relates to an electrodepositable conductive coating composition which contains at least one cationic acrylic polymer, a crosslinking agent and conductive carbon black having an average particle size of about 20 nm or less, a surface area (BET) of about 240-300 m.sup.2 /g and an oil absorption (DBP) of about 100 to 150 ml/100 g. After curing, the conductive coating can be electrocoated with an electrodepositable topcoat having a defect-free appearance and a high degree of gloss.
