摘要:
Wäßrige, flüssige Präparationen von faserreaktiven Farbstoffen, die im wesentlichen aus 5 bis 45 Gew.-% eines wasserlöslichen, faserreaktiven Farbstoffes mit 1 bis 3 β-Sulfatoethylsulfonyl-Gruppen der oben definierten Formel -SO 2 -CH 2 -CH 2 -OSO 3 M, oder aus einer Mischung solcher Farbstoffe, sowie aus 0 bis 10 Gew.-% eines wasserlöslichen, inerten anorganischen Salzes und 45 bis 95 Gew.-% Wasser bestehen; sie besitzen einen pH-Wert zwischen etwa 2,5 und etwa 4,5 und sind weitgehend oder völlig frei von Puffersubstanzen. Die Flüssigpräparationen können für lange Zeit, beispielsweise mehr als 30 Tage, bei einer Temperatur zwischen 0 und 50°C bei deutlich reduzierter Zersetzung in die Vinylsulfonyl-Form aufbewahrt und gelagert werden.
摘要:
The invention provides new monoazo and disazo dyestuffs of the general formulae and their 1:1-copper complex, 1:2-cobalt complex and 1:2-chromium complex derivatives, in which M is hydrogen or an alkali metal, Y a vinyl group or is an ethyl group substituted in the β-position by a substituent which can be split off by means of an alkali, E is a 1,4-phenylene or 1,4-naphthylene radical which is optionally substituted by specific substituents, or is a 2,6- or 2,7-naphthylene radical which is substituted in the 1-position by a hydroxy group and substituted by 1 or 2 sulfo groups, and K is the radical of specific coupling components selected from the acetoacetyl-anilide, naphthol, pyrazolone, aniline, pyridone and naphthylamine series. These monoazo and disazo compounds and the mentioned metal-complex derivatives have very good fibre-reactive dyestuff properties and are suitable for dyeing carbonamide and/or hydroxy groups containing material, in particular cellulose fibre material, according to application and fixation methods usual in the art for fibre-reactive dyes.
摘要:
Water-soluble monoazo dyes of the general formula X - SO₂ - A - N = N - W - - CO - NH - Z - SO₂ - Y
(1) wherein: X and Y are independently selected from vinyl, β-thiosulfatoethyl, β-bromoethyl, β-acetyloxyethyl, β-hydroxyethyl, β-phosphatoethyl, β-methylsulfonyloxyethyl, β-phenoxyethyl, β-sulfatoethyl, β-chlorethyl, β-phenylsulfonyloxy-ethyl and a group of the formula -CH₂-CH₂-NR¹R², in which R¹ and R² are independently selected from hydrogen, lower alkyl and sulfo-substituted lower alkyl; R is hydrogen, lower alkyl or sulfo-substituted lower alkyl; A is a phenylene or naphthylene radical optionally substituted with hydroxy, halogen, lower alkyl, lower alkoxy, carboxy or sulfo; W is a phenylene or naphthylene radical optionally substituted with carboxy, sulfo, amino, carbamoyl unsubstituted or substituted, sulfamoyl unsubstituted or substituted, lower alkyl, lower alkoxy, hydroxy or halogen; Z is a phenylene radical optionally substituted with halogen, lower alkoxy or lower alkyl; and the copper, chromium, cobalt and nickel metallized complex-dyes of said metal-free dyestuffs. These novel dyes yield on cellulose textiles dyeings with high tinctorial strength and purity of shade and with good light and wash fastnesses, particularly a good chlorine wash fastness. They are particularly useful in high temperature dyeing operations and can be prepared into stable aqueous solutions for use in continous dyeing operations. They provide a full range of shades and exhibit superior color yield and leveling in chemical pad steaming dyeing. They build strongly with superior fixation and have superior stability in acidic and alkaline environments.
