CA 2209753
The present invention relates to polyamines which are the reaction products of a) unsaturated oligoesters containing an average of 2 to 4 double bonds per molecule and b) optionally other unsaturated compounds which are suitable as Michael addition acceptors and which contain an average of 1 to 4 double bonds per molecule, with c) (cyclo)aliphatic diamines which contain two primary amino groups, and d) optionally other amino-functional compounds which are suitable as Michael addition donors. The present invention also relates to aqueous, two-component coating compo- sitions containing as binder A) the polyamines according to the invention and B) water dispersible polyisocyanates, and to coatings obtained from these coating compositions.
