| 摘要 |
An aqueous resin dispersion containing as an aqueous resin component a polyamide-modified epoxy-polyamine resin comprising a reaction product of a phenolic hydroxyl group-terminated polyamide compound obtained by the reaction of a polyamine compound containing at least two primary and/or secondary amino groups in a molecule and having a number average molecular weight of 40 to 8,000, a polycarboxylic acid having a number average molecular weight of 100 to 8,000 and a compound containing at least one phenolic hydroxyl group and one carboxyl group in a molecule, a bisphenol compound and a bisphenol diglycidyl ether compound, and an active hydrogen-containing amine compound. Said aqueous resin dispersion is excellent in corrosion resistance and especially suited for use in cathodic electrodeposition coating.
