    摘要: COMPOSITE DYES WHICH ARE MIXTURES OF 1:2 CHROMIUM COMPLEX DYESTUFFS OF TWO DIFFERENT TYPES IN A WEIGHT RATIO OF THE FIRST TO THE SECOND TYPE IN THE RANGE OF FROM ABOUT 4:1 TO 1:4, WHICH DYESTUFFS ARE EACH COMPOSED OF A NAPHTHALENE-AZO-NAPHTHALENE MONAZO DYESTUFF MOIETY AND OF A NAPHTHALENE-AZO-BENZENE-AZO-NAPHTHALENE OR BENZENE-AZO-BENZENE-AZO-NAPHTHALENE DYESTUFF MOIETY LINKED TOGETHER BY THE COMPLEXING CHROMUIM ATOM, DYESTUFFS OF THE FIRST TYPE HAVING A SOLE SULPHONIC ACID GROUP IN FREE OR PREFERABLY IN SALT FORM IN THE MONAZO MOIETY, WHILE THE SECOND TYPE MUST HAVE TWO AND NOT MORE SUCH SULPHONIC ACID GROUPS IN THE COMPLEX MOLECULE, ONE OF WHICH IS IN THE MONOAZO MOIETY WHILE THE SECOND ONE IS LINKED TO A NAPHTHALENE NUCLEUS OF THE MONOAZO MOIETY OR TO ONE OF THE TWO TERMINAL ARYL GROUPS OF THE DISAZO MOIETY, AND DYE COMPOSITIONS CONTAINING THEM TOGETHER WITH DILUENTS AND/OR DISPERSING AGENTS ARE DISCLOSED AS USEFUL FOR THE DYEING AND FOR THE PRINTING OF POLYAMIDE MATERIALS ESPECIALLY FROM ACID MEDIA. A PROCESS FOR COLORING POLYAMIDE MATERIALS WITH THE ACID OF SUCH COMPOSITE DYES AND DYE COMPOSITIONS AS WELL AS POLYAMIDE MATERIALS DYED THEREWITH ARE ALSO DESCRIBED.

    摘要: A process for the preparation of a concentrated storage-stable aqueous solution of the dyestuff of the formula ##STR1## is characterized in that the reaction mixture obtainable from the quinone derivative of the formula ##STR2## by sulphation and subsequent oxidation cyclization, preferably with ammonium, sodium or potassium peroxodisulphate, in oleum is diluted with water or sulphuric acid to a sulphuric acid concentration of 37-50%, preferably 41-43%, and the product which thereby precipitates is separated off and brought to a pH of about 2-6, preferably 3-4, in water with basic lithium compounds, preferably lithium carbonate or lithium hydroxide.

    摘要: Disperse dyes are dischargeable to white with a print paste including a thickening agent, lithium hydroxide, an organic acid, a polyethylene glycol compound, a polyoxyethylene sorbitan fatty acid ester and a polyalkyleneglycol ether. The print paste discharges a number of known disperse dyes, some which have been conventionally thought of as being alkali-resistant. A method of discharge printing of synthetic textile materials (e.g. polyester) is also disclosed.

    摘要: The invention relates to the preparation of storage-stable, concentrated solutions of urea compounds of the formulaF.sub.1 --HN--CO--NH--F.sub.2wherein F.sub.1 and F.sub.2 denote radicals of dyestuffs or dyestuff intermediates containing acid groups by reacting 2 equivalents of amines of the formulaF.sub.1,2 --NH.sub.2with one equivalent of a compound of the formulaCl--CO--Xwherein X is chlorine or an aryloxy radical in the presence of alkaline earth metal ions in the pH range of 4.0 to 8.0, separating off the sparingly soluble alkaline earth metal salt of the resulting urea compounds, adding -- for example -- a salt of lithium of which the anion forms a salt, which is sparingly soluble in the reaction medium, with the alkaline earth metal cation of the urea compound to the suspension of these urea compounds and separating off the alkaline earth metal salt which has precipitated.
