SYNTHETIC RESIN WITH BASIC NITROGEN GROUPS,PREPARATION AND USE THEREOF

摘要

A synthetic resin which carries basic nitrogen groups and is water-dilutable by protonation with acid is obtainable by reacting (A) an epoxy resin having an average molecular weight Mn of from 200 to 6,000 and on average from 1.5 to 3.0 epoxy groups per molecule with (B) a ketimine of a primary amine additionally containing one or more urethane groups and optionally also with (C) a diketimine of a diprimary amine containing no urethane groups and optionally also with (D) a secondary amine which may contain a tertiary amimo group also, a ketimine of a primary monoamine and/or a ketimine of a primary/tertiary diamine.
