Abstract

1298765 Disperse monoazo dyes SANDOZ Ltd 12 Feb 1970 [2 April 1969] 6870/70 Heading C4P The invention comprises dyes of formula wherein R 1 is in both instances H or one is H and the other Cl or Br, R 2 is Cl or Br, A is alkyl, alkoxy, phenyl or phenoxy, B is alkoxy, phenyl or phenoxy, D is alkoxycarbonyloxyalkyl, phenoxycarbonyloxyalkyl, benzoyloxyalkyl, phenoxycarbonylalkyl or alkoxycarbonylethyl, E is alkoxycarbonylalkyl and n is 1 or 2. The dyes are prepared by coupling diazotized 4-halo-2-nitro-anilines with appropriate 3- acylamino - N,N - disubstituted - anilines and are used to dye hydrophobic fibres, in particular polyester fibres, in red shades.
