Abstract

11,172. Newton, P. A., [Farbenfabriken vorm. F. Bayer & Co.]. May 5. Samples furnished. Secondary diazo dyes are obtained by diazotizing the monoazo dyes, produced by combining diazo compounds with aminophenyl-1 : 2-naphthothiazole- 5-oxy-7-sulphonic acids, and combining the diazazo compounds with naphthol-, aminonaphthol-, or acidylaminonaphtholsulphonic acids. The components specified are :-o-toluidine, aniline, xylidine, naphtbylamine, aniline or naphthylamine sulphouic acids ; m- and p-aminophenyl-1 : 2-naphthothiazole- 5-oxy-7-sulphonic acid; 1-naphthol-4- or-5-sulpbonic acid, 2-naphthol-3 : 6-disulphonic acid, 1-amino-8- naphthol-2 : 4-disulphonic acid, 2-acetylamino-5- naphthol - 7 - sulphonic acid. The products are direct cotton dyes. Specification 27,843/04 is referred to. The Provisional Specification refers to azo-dye components in general as last components.
