摘要:
A composition for cationic electrodeposition coating which contains an aqueous dispersion of a cationic aqueous resin and inner-crosslinked micro-resin particles, said inner-crosslinked micro-resin particles comprising an inner-crosslinked addition polymer of an active hydrogen-containing compound (A) and an active double bond-containing compound (B) and having cationic groups. The use of the composition results in an improvement in resistance to edge-corrosion in the coated articles.
