The present invention relates to polyamines which are prepared by reacting a) unsaturated oligoesters having an average of 2 to 4 double bonds per molecule and b) optionally other unsaturated compounds suitable as Michael addition acceptors and having an average of 1 to 4 double bonds per molecule with c) (cyclo)aliphatic diamines having two primary amino groups and d) optionally other amino-functional compounds suitable as Michael addition donors. The present invention also relates to the use of these polyamines as a binder component in lacquers and coating compositions, particularly as reactants for blocked polyisocyanates in one-component stoving lacquers.
