    Abstract: The novel water-soluble disazo dyestuffs consist of two monoazo dyestuff moieties each containing as diazo component an amine of the benzene or naphthalene series and as coupling component an amino-naphthol-mono- or disulfonic acid. The two moieties are bonded to each other via a triazine radical which carries a halogen atom, and is bound to the amino groups of the coupling components and the diazo components contain a fiber-reactive radical of the vinyl sulfone series. To produce the dyestuffs 2 mols of the diazo compound carrying the fiber-reactive radical of the vinyl sulfone series is coupled with 1 mol of a bivalent coupling component consisting of 2 radicals of the aminonaphthol bound to the triazine ring via the amino groups, or two monoazo dyestuffs each synthesized from the aforesaid diazo component and an aminonaphthol-disulfonic acid coupling component are reacted with a 1,3,5-trihalogeno-triazine. The metal-free dyestuffs can be transformed into the corresponding heavy metal complex dyestuffs, preferably copper, cobalt and chromium complex dyestuffs, by treatment with an agent donating a heavy metal cation. The novel dyestuffs are excellently suitable for dyeing and printing fiber material of natural and regenerated cellulose and natural, regenerated and synthetic polyamides. They are distinguished by clear shades, high tinctorial strength, a very good uptake from a long liquor and a good color-build up. The dyeings obtained therewith have a high fastness to processing and in use.

    Abstract: 1376389 Water-soluble reactive mono-azo dyestuffs FARBWERKE HOECHST AG 21 Dec 1972 [21 Dec 1971] 59211/72 Heading C4P Novel dyestuffs of the formula wherein R is H, C 1-4 alkyl, cycloalkyl or aryl; Q is H or OH; Z is -(CH 2 ) 2 OH, -(CH 2 ) 2 OSO 3 H or -CH=CH 2 ; and n is 1 or 2, and their salts, are prepared by conventional diazotization and coupling. Products wherein Z is -(CH 2 ) 2 OH may be converted into the corresponding sulphuric esters and these may be converted into the vinyl compounds by the action of strong alkalis. The new dyestuffs are useful for the dyeing and printing of natural and regenerated cellulose fibres and natural and synthetic nitrogen-containing fibres, especially wool.
