Abstract

1,203,824. Reactive disazo dyestuffs. J. R. GEIGY A.G. 12 Sept., 1968 [13 Sept., 1967], No. 43401/68. Heading C4P. The invention comprises fibre reactive dyestuffs of general formula wherein A is an optionally substituted phenyl or naphthyl radical; B is a coupling component radical; Q is an optionally substituted m- or pphenylene radical; Y is a fibre-reactive group (i.e. forms a covalent bond with the substrate) present in A and/or B; Z is a salt-forming water solubilizing group present in any part of the molecule and which dissociates in neutral water to give an acid reaction; n is 1 or 2 and m is 1 to 7, coupling component radicals B include anilines, phenols, naphthols, naphthylamines or amino naphthols which may be sulphonated; pyrazolones, aminopyrazolones and pyrimidines. Z is preferably a sulphonic, carboxylic acid phosphonic or disulphimide group. The fibre-reactive groups Y include acid radicals which may be unsaturated containing fibre-reactive halogen; nitrohalobenzene carboxylic and sulphonic acids; halo pyrimidines and triazines linked via an imino, acylamino or sulphonylamino group to the dyestuff; halobenzthiazole, quinoxaline, pyridazine or phthalazine carboxylic or sulphonic acids; esterified #-hydroxyalkylsulphone and sulphamoyl groups, and heterocyclic compounds bearing an ammonium or hydrazinium group. The dyestuffs are prepared by diazotisation and coupling or by acylation of a corresponding aminodisazodyestuff. Intermediate monoazo dyestuffs are also prepared. The dyes give orange, red and scarlet shades on cellulosic and natural and synthetic polyamides.
