| titleOfInvention | PROCEDURE FOR THE PREPARATION OF NEW AZOIC DYES |
| abstract | The invention comprises water-soluble dyes containing at least three sulphonic or carboxylic acid groups of formula <FORM:0903408/IV (b)/1> R is the residue of an azo component (free from azo linkages), n is 1 or 2 and Z is the residue of a monoazo dye sulphonic acid bound through an amino bridge. They are prepared by condensing a 2 : 4 : 6-trihalo-1 : 3 : 5-triazine with appropriate aminoazo dyes to yield a mono-halotriazine condensation product. Alternatively the monoazo dye sulphonic acid may be replaced by an amino-naphthol disulphonic acid and the condensate so obtained coupled with a diazotized aniline sulphonic acid. The dyes may be used to colour wool, silk, leather and superpolyamides, but are preferably used to colour cellulose fibres in the presence of an acid-binding agent in yellow and red shades. In an example the monoazo dye sulphanilic acid --> 1-naphthylamine-6-sulphonic acid is prepared and condensed with cyanuric chloride, the primary condensation product is further condensed with 1-amino-8-naphthol-3 : 6-disulphonic acid and the secondary condensation product is coupled with diazotised orthanilic acid. Several similar examples are specified. Specifications 797,946 and 838,337 are referred to. |
