Cationically electrodepositable (gelled) fine particles using, as the base, an epoxy resin-amine adduct having hydrolysable alkoxysilane groups, and a cationic electrodeposition paint composition comprising said fine particles. Said fine particles give a paint film having excellent corrosion resistance and are useful as a rheology-controlling agent for cationic electrodeposition paint. Said electrodeposition paint composition has an excellent edge-covering property, and a paint film formed therewith on an article to be coated can give improved corrosion resistance to the edges of said article and has good surface smoothness.

Cationically electrodepositable fine particles derived from

An electrodeposition paint composition which contains at least one lanthanum compound. When this composition is used, electrolytically deposited coating films exhibiting excellent corrosion resistance can be provided, without using rust inhibiting pigments such as of lead compounds or chromium compounds which are liable to cause environmental pollution.
