Abstract
With the use of a lead-free cationic electrodeposition coating composition containing a sulfonium-modified epoxy resin, an amine-modified novolak-type epoxy resin, and a blocked isocyanate curing agent as a binder resin, wherein the content of volatile organic components is 1% by weight or less, the coating liquid conductivity is 1000 to 2500 μS/cm, and the minimum film-forming temperature of the coated layer electrodeposited on an object to be coated is 20 to 35° C., electrodeposition coating is carried out at or above the temperature which is lower by 2° C. than the minimum film-forming temperature and at or below the temperature which is higher by 6° C. than the minimum film-forming temperature.
