Abstract
The present invention provides a method for forming a multi-layer paint film, comprising: applying a cationic electrodeposition paint containing a block polyisocyanate compound as a cross-linking agent on a surface of a painted matter, applying a water based intermediate coat paint containing a block polyisocyanate compound as a cross-linking agent on an electrodeposition paint film surface without curing the electrodeposition paint film to form an intermediate coat paint film, and then heating to cure both of the electrodeposition paint film and the intermediate coat paint film at the same time to thereby form a multi-layer paint film.
