Cationically electrodepositable paint comprising hydroxyl and cationic group-containing resin and alicyclic epoxy resins

摘要

A resin composition for a cationically electrodepositable paint comprising (A) a resin having hydroxyl groups and cationic groups such as tertiary amino groups prepared from the reaction product of a polyepoxide compound and an secondary amine having hydroxyl group(s), and (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.
