摘要： An object of the present invention is to provide a coated article having excellent finish and corrosion resistance unaffected by a chemical conversion coating solution even if water washing after a pretreatment step is omitted and a pretreatment solution is carried as a contaminant into an electrodeposition coating composition. The present invention provides a method for forming a multilayer coating film comprising a chemical conversion coating film (F1) and an electrodeposition coating film (F2); the method comprising the following steps. Step 1: immersing a metal substrate in a coating film forming agent (1) as a chemical conversion coating solution to form a chemical conversion coating film (F1); and Step 2: without water washing, subjecting the metal substrate to electrodeposition coating using a coating film forming agent (2) as a cationic electrodeposition coating composition (I) to form an electrodeposition coating film (F2).
