Abstract of the Disclosure A cationically electrodepositable finely divided gelled polymer obtained by emulsion-polymerizing, in the presence of a water-soluble or water-dispersible cationic resin, a monomer component (A) comprising (a) a polymerizable unsaturated vinylsilane monomer having a vinylic double bond and a hydrolyzable akloxysilane group, (b) a polymerizable monomer having at least two radically polymerizable unsaturated groups in the molecule, (c) a polymerizable unsaturated monomer having a vinylic double bond and a hydroxyl group, and (d) other polymerizable unsaturated monomer, and a cationically electrodepositable finely divided gelled polymer obtained by emulsion-polymerizing, in the presence of the above finely divided gelled polymer, a monomer component (B) comprising (e) a blocked mono- or polyisocyanate in which the at least one isocyanate group in the molecule is blocked with a radically polymerizable monohydroxy compound, (f) a polymerizable unsaturated monomer having a vinylic double bond and a hydroxyl group, and (g) other polymerizable unsaturated monomer, said cationically electrodepositable finely divided gelled polymer having a core-sheath structure consisting of a core of the polymerization product of the monomer component (A) and a sheath of the polymerization product of the monomer component (B).
