CATIONIC ELECTRO-COATING COMPOSITION

摘要

This invention relates to cationic electro-coating composi-tion which comprises blending which an aqueous dispersion or an aqueous dispersion paste which contains an organic acid-modified bismuth compound in a non-water-soluble state, and which is ob-tained by mixing and grinding a bismuth compound and an organic acid in an aqueous medium. Said cationic electro-coating composi-tion, although containing no lead compounds, is capable of forming an electrocoated film which is excellent in corrosion resistance, appearance, etc.
