Abstract: A base for a printed circuit board is continuously produced by an apparatus comprising at least one degreasing vessel, at least one water pre-washing vessel, at least one electrodeposition coating vessel, at least one electrodepositing liquid-recovering vessel, at least one water post-washing vessel, and a transporting device for intermittently transporting the base successively through the above-mentioned vessels, which apparatus is provided with a device for conveying the base to a predetermined position above one of the above-mentioned vessels, stopping the base at that position, introducing the base into the vessel, keeping the base in the vessel for a predetermined time, and withdrawing the base from the vessel.

Abstract: An electrodeposition resinous paint composition comprising (a) a modified alkyd resin, (b) a melamine resin, (c) a water-soluble silicone resin and (d) an inorganic filler, in which these components (a), (b), (c) and (d) are contained in the following ratios by weight:[(a)/[(a)+(b)]]=0.4-0.9;[(c)/[(a)+(b)]]=0.01-0.1;and[(d)/[(a)+(b)+(c)]]=0.1-1.0.
