Abstract

1276327 Monoazo dyes SANDOZ Ltd 19 Aug 1969 [30 Aug 1968] 41379/69 Heading C4P Monoazo dyes which are free from sulphonic acid groups have the general formula wherein R 1 is NO 2 or an optionally substituted sulphonamide or alkylsulphonyl group; R 2 is Cl or Br; R 3 is H, Cl, Br or CH 3 ; R 6 and R 7 independently represent aliphatic radicals which may be substituted and/or interrupted by one or more hetero atoms. The dyes may be prepared conventionally by diazotization and coupling or alternatively 1 mole of a compound of formula may be acylated with 2 moles of benzoic acid or one of its functional derivatives. The dyes give yellow, orange and brown shades on synthetic or semi-synthetic hydrophobic textile fibres of high molecular weight organic compounds e.g. cellulose acetate, polyamide and polyester fibres.
