Cationically electrodepositable coating composition

The present invention provides a cationic electrodepositable coating composition comprising:

Cationic electrodepositable coating composition and coating method using

This invention provides a cationic electrodepositable coating composition comprising: (A) 30 to 1% by weight of a high-molecular-weight polyurethane resin prepared by reacting (a) an organic polyisocyanate, (b) a high-molecular-weight polyol, and (c) a diol having at least one tertiary amino group, the high-molecular-weight polyurethane resin (A) having a SP value of 9.5 to 12.0 and a number average molecular weight of at least 15,000; and (B) 70 to 99% by weight of an epoxy-type cationic electrodepositable resin.

Electrodepositable coating composition

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,
