Abstract
Trisazo dyes are made by tetrazotizing a p : p<1> - diaminodiphenyl, coupling with H or K acid (1 mol.) in mineral acid solution, coupling the intermediate product formed in alkaline solution with a diazo compound (1 mol.) and finally coupling with a nuclear substitution product of m-aminophenol which only couples in p-position with respect to the hydroxy group. They dye cotton and leather in greenish to blue to black shades fast to acids. Mixed fabrics of cotton, wool, silk and regenerated cellulose are dyed in even shades. In examples the following dyes are described: aniline --> H or K acid \sM benzidine --> 6-chloro-3-aminophenol, 4 - amino - 2 - cresol or 6- methoxy - 3 - aminophenol; tolidine, chloranilines and toluidines are also specified as components. The Specification as open to inspection under Sect. 91 specifies also the following components: sulphanilic acid, dianisidine, 3 : 3<1>-dichlorbenzidine, benzidine-3 : 3<1>-dicarboxylic acid, 4 : 4<1> - diamino - 2 - nitrodiphenyl, o-, m- and p-anisidines, o-, m-, and p-chloranilines, o-, m- and p-toluidines and 1-naphthylamine-4-sulphonic acid. This subject-matter does not appear in the Specification as accepted.
