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

摘要

A resin composition for a cationically electrodepositable paint comprising (A) a resin having hydroxyl groups and cationic groups, (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 obtained by emulsion polymerizing (C-1) a polymerizable monomer containing at least two radically polymerizable unsaturated groups in the molecule, 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 an allyl group in the molecule.
