(57) [Summary] [Structure] A resin having a hydroxyl group and a cationic group, and a cationic electrodeposition coating containing a specific novolac-substituted phenol type epoxy resin as a main component are formed by electrodeposition coating on an object to be coated. The coating film has a minimum hot melt viscosity of 10 5 to 1 A coating method comprising heating until the pressure reaches 0 7 centipoise, then stopping the heating, and optionally applying an intermediate coating composition and / or a top coating composition, and then heating again to cure the coating film. [Effect] It is possible to form a coating film which is excellent in smoothness and has a thick edge portion such as a corner portion, a bent corner portion and a protrusion portion of a cut surface of an object to be coated. |
