Bismuth catalysts useful for curing of cataphoretic deposition coating materials

摘要

Catalysts useful for the curing of, for example, cataphoretic deposition coating materials, including water-soluble bismuth compounds and an epoxy-amine adduct, the preparation of the bismuth compound involving acid being employed in a quantity such that there are less than 2 mol of dissociable protons per mole of bismuth.
