    摘要: Waterinsoluble polyazo dyestuffs of the formulaX(O-OC-D-N=N-K).sub.mIn which K denotes identical or different radicals of a coupling component, X denotes an aliphatic radical which is free of hydroxyl groups and is optionally interrupted by heteroatoms, or an aromatic-carbocyclic, aromatic-heterocyclic or araliphatic radical, D represents an aromatic-carbocyclic or aromatic-heterocyclic radical and m represents the numbers 2 or 3. These dyestuffs are useful as dispersion dyestuffs for coloring synthetic fibers and most especially as pigment dyestuffs for coloring paint, inks, paper, and macromolecular substances and for admixing with other substances such as inorganic white pigments including titanium dioxide.

    摘要: Fluctuations in concentration of the starting materials during continuous diazotization are taken into account by passing a component stream from the receiver to the diazotization vessel through an analyser where, for a short residence time, the nitrite content is determined by an electrochemical measuring technique. A required nitrite excess is adjusted in the receiver on the basis of this measurement. By virtue of the pH-value, however, a diazotization reaction still does not take place in the receiver.

    摘要: Reactive dyestuffs of the formula ##STR1## in which Q and P are hydrogen or sulfonic acid but cannot simultaneously have the same meaning; andD is a radical of an aromatic-carbocyclic or aromatic-heterocyclic diazo component which contains a reactive group; are disclosed. These are useful for the dyeing and printing of materials containing hydroxyl groups or amide groups, such as textile fibres, filaments and fabrics of wool, silk and synthetic polyamide and polyurethane fibres, and for the wash-fast dyeing and printing of natural or regenerated cellulose, the treatment of cellulose materials being appropriately carried out in the presence of acid-binding agents and if appropriate by the action of heat, in accordance with the known processes for reactive dyestuffs.
