摘要：
Colorants are obtained by reacting a dyestuff which is free from ionic groups and has.gtoreq.2 NH.sub.2 groups which are preferably arranged in such a manner that they do not participate in the resonance of the chromophore with such an amount of a (cyclo)aliphatic diisocyante so as to form an adduct that still contains at least two free NCO groups, and subsequently reacting this adduct with a (cyclo)aliphatic diamine, to form an adduct suitable for dyeing and pigmenting macromolecular substances, in particular for coloring PUR-based paints, coatings and laminates.
