A cationically electrodepositable finely divided gelled polymer obtained by, in the first step, emulsion polymerizing (A) a monomer component comprising

Cationically electrodepositable finely divided gelled polymer and

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.
