Process for electrocoating

A method for preparing electrodeposition coating on an uncoated metallic article which is characterized in that the article desired to be coated is first immersed into an aqueous bath consisting essentially of 4- 10 weight percent of water soluble or water dispersible resin and 0.1 to 0.8% by weight (on the basis of resin solids content) of at least one water soluble oxyacid salt selected from the group consisting of stannates, molybdates, tungstates, vanadates and borates, said article is connected to the positive electrode and supplied with DC electric voltage in the range of 30 to 300 Volts for 30 seconds to 10 minutes, then said article is rinsed with water and dried, and heated at a temperature in the range of 130 to 300.degree. C. for 30 seconds to 60 minutes to cure the resinous component in the obtained electrodeposition coating.
