<P>PROBLEM TO BE SOLVED: To provide a method for forming multilayer anionic electrodeposition coating film, by which an anionic electrodeposition coating film of a second coat can be thickened and an excellent appearance can be obtained. <P>SOLUTION: The method for forming multilayer anionic electrodeposition coating film includes: a first step of electrodepositing an anionic electrodeposition coating (A) containing a particulate metal oxide to a substrate to form an uncured anionic electrodeposition coating film (A); a second step of electrodepositing an anionic electrodeposition coating (B) to the substrate on which the uncured anionic electrodeposition coating film (A) is formed to form an uncured anionic electrodeposition coating film (B); and a third step of baking and curing the uncured anionic electrodeposition coating film (A) and the uncured anionic electrodeposition coating film (B) at a time, wherein a resistance value of the uncured anionic electrodeposition coating film (A) is 25-190 kΩ cm<SP POS="POST">2</SP>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
