| abstract | Reactive dis- and tris-azo cpds. of formula (I), having central hydroxy-disulpho-naphthylene gp., are new. Z-N=N-Naph-N=N-K (I) Naph =hydroxy-disulpho-naphthylene gp. of formula (II); one of B1 and B2 = H and the other = SO3H; K = radical of coupling component of naphthyl or heterocyclic series; Z = the radical of a OH-free diazo component of benzene or naphthalene series or of monoazo cpd.; K and/or Z contains a fibre-reactive gp. of formula (IIIA), (IIIB) or (IIIC): -SO2-Y (IIIA); -CONR1-(CH2)n-SO2-H (IIIB); X = halogen, 3-carboxy-pyridin-1-yl or 3-carbamoyl-pyridin-1-yl; T = X; OH; 1-4C alkoxy; phenoxy; 1-4C alkylthio; morpholino; amino opt. with inert substit(s).; or a reactive gp. of formula (IVA-F): -N(R2)alk(R3)-SO3-Y (IVA); -N(R1)-alk-Q-alk'-SO2-Y (IVB); -NR1-arylene-SO2-Y (IVC); -N(R1)-arylene-(alk)m-W-alk'-SO2-Y (IVD); -N(R1)-arylene-NH-CO-Y1 (IVF); R2 = H; 1-4C alkyl, opt. substd. by OH, SO3H, OSO3H, COOH or CN; or -alk(R3)-SO2-Y; R3 = H, OH, SO3H, OSO3H, COOH, CN, halogen, 1-4C alkoxycarbonyl, 1-4C alkanoyloxy, carbamoyl or -SO2-Y; alk, alk' = 1-6C alkylene; arylene = phenylene or naphthylene, opt. substd. by SO3H, COOH, 1-4C alkyl, 1-4C alkoxy or halogen; Y1 = -CHX2-CH2X2 or -CX=CH2 (X2 = Cl or Br); Q = -O- or -NR1-; W = SO2-NR2-, -CONR2- or -NR2CO-; m = 0 or 1; R1 = H or 1-8C alkyl; Y = vinyl or -CH2-CH2-U (U = a gp. released under alkaline conditions); n = 1-6. |
