Abstract

A synthetic resin which carries basic nitrogen groups and is water-dilutable by protonation with acid is obtainable by reacting PA0 (A) an epoxy resin having an average molecular weight M.sub.n of from 300 to 6,000 and on average from 1.5 to 3.0 epoxy groups per molecule with PA0 (B) a ketimine of a primary amine additionally containing one or more urethane groups and optionally also with PA0 (C) a diketimine of a diprimary amine containing no urethane groups and optionally also with PA0 (D) a secondary amine which may contain a tertiary amino group also, a ketimine of a primary monoamine and/or a ketimine of a primary/tertiary diamine.
