摘要
Polymeric reaction products which become water-thinnable on protonation with an acid and are suitable for use in the form of aqueous dispersions as additives in electrocoating baths are formed from A. a butadiene/acrylonitrile copolymer which contains primary and/or secondary amino groups and B. an epoxy compound having an average molecular weight of from 140 to 10,000 and containing on average from 1.5 to 3 epoxy groups per molecule, the amount of (A) being such that 1.05 moles or more of primary and/or secondary amino groups of component (A) are present per mole of epoxy groups of component (B).
