Abstract

1406921 Monoazo dyes BAYER AG 5 Jan 1973 [2 March 1972] 741/73 Heading C4P New monoazo dyes of formula wherein R 1 is C 1-4 alkyl which may be substituted by halogen, CN or phenyl, R 2 is H, optionally substituted alkyl or phenyl, R 3 is optionally substituted sulphoalkyl or sulphophenylmethyl, R 4 is, H, halogen, optionally substituted alkyl or alkoxy, R 5 is H, Cl, Br, CH 3 , C 2 H 5 or acylamino, R 6 is Cl, Br, CF 3 or SO 2 R 1 and R, is Cl or Br are prepared by coupling a diazotized 4-alkylsulphonyl-aniline with an appropriate N-substituted-aniline. They are used to colour natural and synthetic polyamide fibres in orange to bluish-red shades.
