Resin composition for cationically electrodepositable paint comprising alicyclic epoxy resins and emulsion polymerized, finely divided gelled polymers

A resin composition for a cationically electrodepositable paint comprising

• (A) a resin having hydroxyl groups and cationic groups and being obtained by reacting a polyepoxide compound obtained from a polyphenol compound and epichlorohydrin with a cationizing agent,
• (B) an epoxy resin having at least 2 epoxy functional groups each of which comprises an epoxy group directly bound to an alicyclic ring and/or bridged alicyclic ring on average per molecule, and
• (C) a finely divided gelled polymer as principal components, wherein said finely divided gelled polymer is one obtained by emulsion polymerizing
• (C-1) a polymerizable monomer containing at least two radically polymerizable unsaturated groups, and
• (C-2) a radically polymerizable unsaturated monomer other than the one mentioned in (C-1) above
• in the presence of a reactive emulsifier containing one allyl group.
