    摘要： The present invention simplifies the complicated dyeing process using a naphthol dye, and provides a modified regenerated cellulose fiber which enables dyeing in different colors by combining the modified regenerated cellulose fiber and other fibers by means of mixed spinning or union knitting/weaving. A modified regenerated cellulose fiber can be obtained by containing 0.5-3.0% by weight of a grounder of naphthol dye to the regenerated cellulose fiber in a matrix consisting of the regenerated cellulose fiber, wherein the grounder is selected from the group having a medium to high level of affinity to the regenerated cellulose fiber. A variety of dyed fiber products can be obtained by treating yarn or knitted/woven fabric made of the above modified regenerated cellulose fiber with a developer of naphthol dye.

    摘要： A universally usable process for preparing azo dyestuffs by oxidative coupling consists in carrying out the oxidation in the presence of redox mediators with a standard potential of 0.2-1.5 volts and, if appropriate, an additional oxidizing agent with a standard potential of 0.25-2.5 volts, wherein the sum of the oxidation equivalents should be at least 4. The preferred redox mediator is iodine. The process is particularly suitable for the preparation of heteroaromatic azo dyestuffs using an aniline coupling component.

    摘要： Liquid compositions of nitro group-containing aniline compounds containing no sulfonic acid and/or carboxylic acid groups and having a melting point of below 140.degree. C., especially those suitable for use as diazo component in ice color dyeing, which contain 20 to 70% of this nitro-aniline, 5 to 80 weight % of a castor oil oxethylated with 25 to 60 mols of ethylene oxide, and 5 to 65 weight % of N-methyl-pyrrolidone as solvent. By simply mixing these components clear solutions are obtained which can be diazotized within a few seconds by means of an aqueous sodium nitrite solution and thus give diazonium salt solutions free from residue. These diazonium salt solutions can be used in simple manner and very advantageously as developing baths or liquors for producing water-insoluble azo dyestuffs on the fiber according to the ice color technique.

    摘要： o-Aminophenol ethers deriving from lower alkylene glycols, lower alkylene polyglycols and the corresponding mono-lower alkyl ethers which may be substituted in the phenyl nucleus by halogen or nitro, are useful as diazo components in the "all-in" printing process for preparing developing dyes on cellulose. In this process the printing paste contains the alkaline solution of the coupling component, a dispersion of the amine, sodium nitrite and a thickening composition and developing of the dye is brought about with acidic means, followed by or combined with a heat treatment.

    摘要： Aqueous dispersions of primary aromatic amines which contain at least 30 per cent by weight of a primary aromatic amine, a water-soluble condensation product which contains 2 to 6 radicals of oxalkylated aromatic compounds carrying hydroxy or carboxy groups, these radicals being linked to each other over methylene groups either directly or via radicals of aromatic compounds, and containing water and, optionally, a polyvalent alcohol. These dispersions are very stable and storable for a very long period, the primary aromatic amines therein are so finely dispersed that they do not precipitate; they have a low viscosity and can easily be introduced with stirring in a dyeing liquor or in pastes. These novel dispersions are suitable for the preparation of water-insoluble azo dyestuffs according to the methods of ice-color technique by mixing them with a sodium nitrite solution and a hydrochloric acid solution for diazotization thereafter, the diazo compounds obtained may be used in known and usual manner for the preparation of the dyestuffs.
