    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.

    Abstract: Oligomeric azo dyes (I) have alternating tetrazo components and coupling components in >= 4 units consisting of an optionally substituted benzene tetrazo component and coupling component derived from an amino-1-naphthol-mono- or di-sulfonic acid, optionally partly replaced by a benzene derivative. (I) contain >= 4 units of formula (II). D = a tetrazo component of formula (III); and K = a divalent residue of a coupling component of formula (IV), up to 80 mole-% of which may be replaced by a coupling component of formula (V); R = H, hydroxysulfonyl (SO3H), halogen, hydroxyl (OH), methoxy, cyano (CN), carboxyl (COOH), 1-4 C alkoxycarbonyl, carbamoyl, sulfamoyl, mono- or di-(1-4 C)-alkyl-carbamoyl or -sulfamoyl; R = H, SO3H or halogen; R = H or 1-4 C alkyl, optionally substituted by OH, CN, COOH, SO3H, (m)ethoxycarbonyl or acetoxy; n = 1 or 2; R , R = OH, 1-4 C alkoxy, amino, morpholino, NHAlk or N(Alk)2; R = H, COOH, SO3H, 1-4 C alkyl, 1-4 C alkoxy, 1-4 C alkoxycarbonyl, carbamoyl, sulfamoyl, mono- or di-(1-4 C)-alkyl-carbamoyl or -sulfamoyl, NHAlk or -N(Alk)2; and Alk = 1-4 C alkyl, optionally substituted by OH, CN, mono- or di-(1-4 C)-alkylamino, amino, COOH, SO3H, 1-4 C alkoxycarbonyl, carbamoyl, sulfamoyl, mono- or di-(1-4 C)-alkyl)-carbamoyl or -sulfamoyl or morpholinocarbonyl and optionally with one oxygen atom in the chain. An Independent claim is also included for the preparation of (I).
