Abstract
1451252 Water-soluble disazo dyes SANDOZ Ltd 3 Jan 1974 [8 Jan 1973] 00213/74 Heading C4P Novel dyes which in free acid form are of formula where each X is halogen, R 1 is H, halogen, NO 2 , OH, SO 3 H, alkyl, alkoxy, alkylamino or acylamino in which the acyl group is derived from an organic carboxylic acid and R 2 is H, OH, alkyl, alkoxy or SO 3 H are prepared by coupling a diazotized amine of formula with 2 - amino - 8 - hydroxy - naphthalene- 6-sulphonic acid under neutral to acid conditions. The novel dyes may be used to dye textile materials, paper or leather and give red shades. The textiles may be for example of natural or synthetic polyamides, polyurethanes, polyvinyl alcohol, basically modified polyacrylonitrileor polypropylene, ornatural or regenerated cellulose.
