Abstract
Substantive polyazo dyes are made by coupling diazo compounds of disazo dyes of the general formula A-N = N-M1-N = N-M2-NH2 (wherein A = the residue of a benzene or naphthalene derivative, M1 = the residue of 1-naphthylamine or 1-naphthylamine-6-and/or 7-sulphonic acid, and M2 = the residue of an aminohydroquinone dialkyl or diaralkylether) with monoazo dyes: amine --> (acid) J acid. They yield green-blue shades on cotton. In an example the following dye is described: aniline-o-sulphonic acid --> 1-naphthylamine-7-sulphonic acid --> aminohydroquinone dimethylether --> J acid (acid) \sM metanilic acid. Other components specified are: aniline-2 : 5-disulphonic acid, 2-naphthylamine-4 : 8-disulphonic acid or 4-chloraniline-3-sulphonic acid; aminohydroquinone di-ethyl- or dibenzyl ether. Specifications 15403/09, [Class 2 (iii)], 352,368, 352,878, and 432,122 are referred to.
