摘要：
A synthetic resin carrying basic nitrogen groups, its preparation, coating materials prepared from this resin, and a process for cathodic electrocoating.This synthetic resin is obtained by reacting(A) an epoxy resin which(B) a diketimine of a diprimary amineand, if required,(C) with a secondary amine, which may additionally contain a tertiary amino group, with a ketimine of a primary monoamine and/or with a ketimine of a primary/tertiary diamine,a diketimine obtained from(B.sub.1) a ketone and(B.sub.2) a branched aliphatic diprimary diamine of 5 to 9 carbon atoms and/or(B.sub.3) one or more diaminodiamides which are obtained by condensation of 2 moles of diamine (B.sub.2) and 1 mole of a dicarboxylic acidbeing employed as component (B).After protonation with an acid, this synthetic resin is useful as a binder for cathodic electrocoating.
