A composition for visible light sensitive electrodeposition coating which comprises (A) a photocurable resin having light sensitive groups capable of being crosslinked or polymerized by light irradiation and ionic groups, (B) a sensitizer which is excited by absorption of visible light and has a property to interact with the resin (A), (C) a water-insoluble polymerization initiator, and optionally, (D) at least one specific nitrogen-containing compound; and an image-forming method which comprises (i) coating the surface of a conductor by electrodeposition with the aforesaid composition, (ii) exposing the resulting film by electrodeposition by partially irradiating the film with visible light, and then (iii) contacting the resulting film with a developing solution to remove the unexposed areas.
