Synthetic resin carrying basic nitrogen groups, and its preparation

摘要: A synthetic resin which carries basic nitrogen groups and can be diluted with water as a result of protonation an acid obtained by reacting epoxy resin, having mean molecular weight M n from 300 to 6,000 containing on average 1.5 3.0 epoxide per molecule, diketimine primary diamine and, if appropriate, secondary amine, may additionally contain tertiary amino group, ketimine monoamine and/or primary/tertiary diamine. These resins are useful binders for coating agents, in particular the cathodic electrocoating electrically conductive substrates.
