    摘要: A method for forming a multilayer paint film comprising the steps of forming an uncured film on a substrate with a cationically depositable paint on a substrate, further coating an aqueous paint on the uncured film of the electrodeposited film in a wet-on-wet manner, and then curing with heating the both films,wherein (i) the electrodeposited film of the cationically electrodepositable paint has a film weight reduction after curing with heating of 10% by weight or less; andwherein (ii) the aqueous paint is composed mainly of(a) a polyester resin optionally modified with a urethane and having an acid value within the range of 10 to 100 and a hydroxyl value within the range of 20 to 300; and(b) a water-soluble or -dispersible amino resin.
