According to the present invention, provided is a cationically electrodepositable coating material comprising a resin for a cationically electrodepositable coating material, a hydrotalcite-like solid solution having a specific composition and, if necessary, a basic bismuth compound and/or an organic acid salt thereof. Such cationically electrodepositable coating material forms a coating film which is excellent in performances such as an edge corrosion-preventive property, a throwing power, a chemical resistance and a smoothness without adding harmful substances such as lead compounds and chromium compound.

Cationically electrodepositable coating material

Electrodeposition coating composition

This invention relates to cationic electro-coating composition 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 obtained by mixing and grinding a bismuth compound and an organic acid in an aqueous medium. Said cationic electro-coating composition, although containing no lead compounds, is capable of forming an electrocoated film which is excellent in corrosion resistance, appearance, etc.

Cationic electrodeposition paint composition

There is disclosed a cationic electrodeposition coating composition containing bismuth lactate derived from a lactic acid, whose L-isomer content is at least 80% by weight, or bismuth methoxyacetate in a form of being dissolved in an aqueous medium. The electrodeposition coating composition can form a coating film having excellent anticorrosivity and finishing property without containing a lead compound.
