    Abstract: Compounds of the general formula I I where E is -CH= or -N=, K is the radical of an amine or of a coupling component of the benzene, naphthalene, pyrazole, pyridine, pyrimidine, quinoline or isoquinoline series, or the radical of a 1,3-dicarbonyl compound which can be coupled, X is -O- or -COO-, Y is -O-, -COO- or -NH-, Z1 and Z2 independently of one another are unsubstituted or substituted alkyl or cycloalkyl, and one of them may furthermore be unsubstituted or substituted aryl, or Z1 and Z2 together with the nitrogen atom are a heterocyclic radical, and Z is unsubstituted or substituted C2- or C3-alkylene, from 1 to 4 sulfonic acid groups can be present and the rings A and B can be further substituted or can carry a fused benzene ring. The compounds of the present invention are suitable for dyeing or printing natural or synthetic N-containing materials, i.e., wool, leather or polyamide or polyurethane fibers, as wells as for coloring inks. The colored salts with amine bases are insoluble in water, but soluble in organic solvent. These colored salts can be used for dyeing organic liquids, resins or surface coatings, wood stains, paste for ball point pens, for coloring anodized aluminum, or for spin-dyeing, i.e., cellulose ester fibers for polyamide fibers.
