Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electrodeposition coating method which can give appearance uniformity high enough to satisfy very severe appearance requirements in the field of electronic appliance enclosures by attaining an enclosure appearance similar between side areas and top and bottom areas by improving the dispersibility of particles, to provide a composite coating film, and to provide an article coated by electrodeposition.SOLUTION: The electrodeposition coating method comprises using an electrodeposition liquid prepared by dispersing in an electrodeposition coating material a dispersant composition formed by binding, by using a coupling agent, disperse particles with (A) an anionically or cationically electrodepositable (meth)acrylic resin of a weight-average molecular weight of 1,000-40,000 obtained by polymerization in a solvent containing an aprotic polar solvent.
