    Abstract: Azoxy dyes of the general formula I in the form of the free acid where n is 0 or 1, each R 1 is selected from the group consisting of methoxy, hydroxyl and carboxyl, each R 2 is selected from the group consisting of carboxyl, amino, C 1 -C 4 -alkylamino, allylamino, benzylamino and methoxycarbonylmethylamino, and the phenyl rings A may additionally be substituted by C 1 -C 8 -alkyl, unsubstituted or methyl- or halogen-substituted phenyl, hydroxyl, amino, nitro, halogen, carboxyl, N-benzylcarbamoyl, unsubstituted or nitro-, halogen-, C 1 -C 4 -alkoxy- or acetoxy-substituted phenylcarbamoyl and naphthylcarbamoyl or be benzofused, their copper complexes, a process for preparing the copper complex dyes, azoxy dyes of the formula I in their partially or completely deacylated form, their copper complexes, colorants comprising these azoxy dyes and/or their copper complexes and also their use for dyeing and printing natural or synthetic substrates.

    Abstract: New cationic sulfonic acid dyes are bis(ammoniumalkyl-oxy-, -carbonyl, -carbonyloxy-, -carbonylimino-, -iminocarbonyl-phenylazo)-aminonaphtholsulfonic acid compounds giving fast dyeing for paper. New cationic sulfonic acid dyes are bis(ammoniumalkyl-oxy-, -carbonyl, -carbonyloxy-, -carbonylimino-, -iminocarbonyl-phenylazo)-aminonaphtholsulfonic acid compounds of formula (I); A , A = oxy, carbonyl, carbonyloxy, carbonylimino, iminocarbonyl, carbonyl-(1-4 carbon (C))-alkylimino or (1-4C)-alkyliminocarbonyl; B , B = 1-6 C alkylene, optionally with 1 or 2 non-adjacent oxy, imino or optionally hydroxy- (OH) or methoxy-(OMe) substituted 1-4C alkylimino groups in the chain; R = hydrogen (H) or 1-4C alkyl, optionally substituted by OH, OMe, chloro or phenyl; R = H or 1-4C alkyl; or NR R = 5-6-membered saturated heterocyclyl, optionally with another nitrogen (N) or oxygen (O) heteroatom; R , R = H, 1-4C alkyl (optionally substituted by OH, halogen or OMe), halogen, nitro or 1-4 C alkoxy; Q = H, 1-10C alkyl, optionally with 1-4 non-adjacent oxy, imino or optionally OH- or OMe-substituted 1-4 C alkylimino groups in the chain and optionally substituted by OH, halogen or phenyl; or NQ Q , NQ Q = 5-6-membered heterocyclyl, optionally with another N or O heteroatom; An = anion.
