Abstract

974. Farbenfabriken vorm. F. Bayer & Co. April 20, 1910, [Convention date]. Samples furnished. Trisazo dyes are obtained by combining the diazo compound of an acidyl-p-phenylenediamine or a substitution product thereof, such as 2-oxalylamino-4-chlor-5-aminoanisol cr 5-acetylamino- 2-aminotoluene, with a middle component, rediazotizing and combining with the same or a different middle component, diazotizing again and combining with a pyrazolone or substitution product thereof, and finally splitting off the acidyl group. The products dye cotton violet to blue shades and can be diazotized on the fibre and developed with #-naphthol &c. According to an example, the following components are used : -oxalyl-p-phenylenediamine, 1-naphthylamine-6-sulphonic acid, 1-naphthylamine-6-sulphonic acid, 1-phenyl-3-methyl-5-pyrazolone. The following pyrazolones are also specified : - 1 - sulphophenyl - 3 - methyl - 5 - pyrazolones, 1-naphthyl-3-methyl-5-pyrazolones and their sulphonic acids, 3 - methyl - 5 - pyrazalones 1- carboxyaryl-3-methyl-5-pyrazolones. Other middle components specified are 1-naphthylamine and its 7-sulphonic acid, aminonaphthol sulphonic acids, m-toluidine, and cresidine.
