AQUEOUS CATHODIC ELECTRO-DEPOSITION LACQUER COATING COMPOSITIONS AND METHOD OF USING THE SAME

摘要

Aqueous cathodic electrodeposition lacquer coating compositions are provided which comprise (A) certain water soluble synthetic resin binders containing amino groups; (B) crosslinking reagents which react with resin (A), and (C) certain soluble or insoluble transesterification catalysts for the crosslinking reagents. Methods of forming baked finish coatings which are cathodically deposited on electrically conductive surfaces using the lacquer coatings are also disclosed.
