Definitions

  • the present invention relates to new and valuable metal compounds of azo-dyestuffs derivmg from metals of atomic weights ranging from 52 to 58,7. These metal com, pounds may contain either one metal'alone or several metals. In the latter case one or several metals may also not belong'to the above mentioned range of atomic weights.
  • the dyestuffs according to the present invention are made by treating the poly-aZo-dyestuff of the general formula in which R and R are aryl residues, from which at least the one of these contains morda'nt bindinggroup.
  • the sulfogroups being in meta-positionto the OH- groups, further in which, the two azo-groups are linked in ortho-position to the OH- groups and in which at most one OH-group stands 1n 8-pos1t1on,,w1th agents yielding metals of atomic Weights ranging from 52 to 58.7,.these agents being chosen in such a- Way that either one or several metals enter the dyestufi' molecule whereby in the latter case other metals may alsoenter the dyestufi molecule.
  • the treatment may beapplied in the course ofthe production of the said polyazo-dy'estufi' or to the finished dyestuff, either in the fiber, in the dye-bath or in substance.
  • These dy'estufi's do not dye the artificialsilks from cellulose esters or cellulose ethers.
  • HOaS- Eaaamfole 2 In presence of sodium carbonate 53,5 parts of the dyestuif 2: 1-azonaphthalen e-5 5- dihydroxy-2-amino-7 7-disulfonic acid are coupled with lO parts of diazotized picramic acid and the azo-dyestuff of the formula powder which dissolves in water, dilute alkalies and concentrated sulfuric acid to greenish-grey solutions. It dyes cotton, viscose and silk fast uniform green-grey tints.
  • Example 4 54 parts of thesodium salt of the monoazo-dyestuff obtained in acetic acid solution from dia-zotized 2-amino-5-hydroxynaphtha- 'lene-7-sulfonic acid are dissolved in 600 parts of Water and this solution is mixed with parts of sodium carbonate. The diazo-compound from 32 parts of anthranilic acid is then added and the dyes'tulf formed after some time is isolated. By boiling the dyestuf't' of the formula OOH parts of 4-chloro-2-amino l-phenol and after thus formed with; a solution of chromium some time the diaZo-compound from 19,9 fluoride containing 25-parts of Cr o in 3000 parts of picramic acid.
  • the chro; azo-dyestufi thus produced of the-formula mium compound of the new dyestufl' is is filtered and dissolved in 4000 parts of hot water. There are then added 30 parts of @150 in the form of a chromium fluoride solution and the whole is heated for 24 hours in a reflux apparatus.
  • Example 5 54 parts of the mono-azo dyestuif obtained from diazotized 2-amino 5-hydroxynaphthalene-7-sulfonic acid and 2-amino-5-hydroxynaphthalene-'Y-sulfonic acid (acetic acid coupled) are dissolved. in 500 parts of water and combined in the presence of sodium carbonate with the diazo-conipound from 22,3 parts of l-chloro 2 amino 1 phenol 6 sulfonic acid.
  • the dyestuff of the formula By treating the azo 'dyestufi of the first paragraph of'this example with a solution of 25 sloin on parts of copper sulfate and 20 parts of Cr 3 in the form of a chromium salt (fluoride,
  • the metal compounds deriving from a group of metaljstheatomic weights of which range general formula in which R and R are benzene radicles, from which at least the one of these contains a mordant binding group in ortho-position to the -N N- group, in which one of the ws and one of the ys stand for an OH-group and the other w and the other 3/ for a hydrogen atom, one of the ws and one of the zs represent a SO H-group, and the other a and the other a a hydrogen atom, the sulfo-groups being in meta-position to the OH-groups, further in which the two azogroups are linked in ortho-position to the OH-groups, and in which at most one OH- group stands in 8-position, which products are when dry dark colored powders, soluble in water and dilute alkalies to blue to grey-blue and grey solutions and in concentrated sulfuric acid to blackish-
  • the OH-groups further in which the two azogroups are linked inortho-position to the OI-I-groups, and in which at most one UH- vgroup stands in 8-position, containing besides a group of metals the atomic weights of which range from 52 to 58.? still ther metals which products are when dry dark col.- ored powders, soluble in water and dilute alkalies to blue to grey-blueand grey soluin which R and R are benzene radicles, contions and in concentrated sulfuric'acid to blackish-blue to blue and grey solutions, and dyeing vegetable fiber and especially artificial silk from so-called regenerated cellulose fast violet to blue and grey tints.
