| titleOfInvention | Novel monoazo and disazo colorants from aminoalkylanilines and bis(aminoalkyl)anilines |
| abstract | Water-insoluble azo dyestuffs of the formula <IMAGE> and water-soluble acid addition salts thereof useful for coloring natural fibers, synthetic fiber-forming material and cellulosic materials as well as in the manufacture of paper, varnishes, inks, coatings and plastics in which A represents an azoic coupling radical derived from a coupling component selected from the group consisting of arylides of hydroxy-substituted carbocyclic aromatic carboxylic acids, 1-aryl-5-hydroxy-pyrazoles, 6-amino-1-naphthol-3-sulfonic acid, and compounds having an enolizable ketomethylene group of the formula <IMAGE> R is hydrogen, lower-alkyl, lower-alkoxy or halogen; R2 is hydrogen, lower-alkyl, lower-alkoxy, halogen, aminomethyl or 2-aminoethyl with the proviso that A is other than beta -naphthol when R2 is aminomethyl or 2-aminoethyl; R1 and R3 are the same or different and are each hydrogen, lower-alkyl, lower-alkoxy, halogen or aminomethyl with the proviso that at least one of R1 and R3 is aminomethyl when R2 is other than aminomethyl or 2-aminoethyl; and n represents an integer whose value is 1 or 2 and corresponds to the number of azo linkages, which dyestuffs are obtained by coupling a diazotized amine of the formula <IMAGE> in which R, R1, R2 and R3 are as defined above with said coupling component. |
