摘要

A cathodic electrodeposition paint for protecting a surface-untreated colled rolled steel substrate comprises a cationic film-forming epoxy resin and a crosslinker, both dispersed in an aqueous medium containing a neutralizing agent, and additionally contains, as an anticorrosive agent, a combination of a cerium compound with either a polyvalent metal phosphomolybdate or a copper compound.
