Description

Verfahren zur Herstellung von gelben Färbungen auf Celluloseestern oder -äthern Es ist bekannt, Acetylcellulose mit monosulfierten Nitrodiarylaminen zu färben. Die Verwandtschaft dieser Farbstoffe zur Acetatseide ist sehr gering, so daß nur sehr helle Färbungen damit erzielt werden können. Ferner ist es bekannt, daß Farbstoffe, welche durch Einwirkung von Nitrodiazoverbindungen auf Diphenylam nsulfosäure oder von Nitrosulfodiazoverbindungen auf Diphenylarnin entstehen, kräftige Färbungen, auf Acetylcellulose ergeben. Der Wert aller dieser Farbstoffe ist, soweit @es sich um gelbe Farbstoffe handelt, gering, da sie entweder phototrope oder mäßig lichtechte oder stark Säureempfindliche Färbungen ergeben.Process for the production of yellow colorations on cellulose esters or ethers It is known to use acetyl cellulose with monosulfated nitrodiarylamines to color. The relationship between these dyes and acetate silk is very low, so that only very light colors can be achieved with it. It is also known that dyes, which by the action of nitrodiazo compounds on Diphenylam nsulfonic acid or from nitrosulfodiazo compounds on diphenylamine, strong Stains on acetyl cellulose. The value of all of these dyes is so far @these are yellow dyes, low as they are either photochromic or moderate result in lightfast or strongly acid-sensitive colors.

Es ist nun gefunden worden, daß alle diese Nachteile vermieden werden, wenn man zum Färben solche monosulfierten Nitroarylazodiarylamine verwendet, welche wenigstens eine Nitrogruppe im Diarylaminkomplex enthalten. Solche Farbstoffe erhält man durch Kondensation von Nitro- oder Dinitrochlorbenzolsufosäure mit Aminoarylazofarb,stof£en oder durch Kondensation von Nitro- oder Dinitrochlorbenzolen mit monosulfierten Aminoazofarbstoffen. Dabei können die fertig gebildeten Farbstoffe noch andere Gruppen, wie z. B. NH., NH # CH3 USW., OH, OCH3 usw., enthalten. Beispiele r. t kg Acetatseide wird in einem Färbebade, welches zog des Farbstoffes .1-Benzola7o-a', 6'-dinitro-q.'-sulfodiphenylamin enthält, in der üblichen Weise mit oder ohne Zusatz von Salzen oder Säuren oder Schutzkolloiden 3/4 bis i Stunde lang, bei 6o bis 70° C gefärbt. Die erhaltene kräftige :goldgelbe Färbung zeichnet sich durch hervorragende Echtheits- eigenschaften. aus. Ferner ist der Farbstoff besonders wertvoll dadurch, daß er in Kom- bination mit anderen Farbstoffen zu z. B. braunen oder grünen Farbtönen nicht plioto- trop ist. a. i kg Acetatseide wird in der im Bei- spiel i beschriebenen Weise mit 2o g des Farbstoffes 4-Benzolazo-4'-nitro-2'-sulfo.diphe- nylamin gefärbt. Die erhaltene gelbe Färbung besitzt gleichfalls gute Echtheitseigenschaften.It has now been found that all of these disadvantages are avoided if monosulfated nitroarylazodiarylamines which contain at least one nitro group in the diarylamine complex are used for dyeing. Such dyes are obtained by condensation of nitro- or dinitrochlorobenzenesulfonic acid with aminoarylazo dyes or by condensation of nitro- or dinitrochlorobenzenes with monosulfated aminoazo dyes. The finished dyes can also contain other groups, such as. B. NH., NH # CH3 ETC , OH, OCH3, etc. contain. Examples r. t kg of acetate silk is put in a dye bath which contains the dye .1-Benzola7o-a ', 6'-dinitro-q .'-sulfodiphenylamine, in the usual way with or without the addition of salts or acids or protective colloids 3/4 to 1 hour long, colored at 60 to 70 ° C. The strong: golden yellow color obtained is characterized by excellent authenticity properties. the end. Also is the dye particularly valuable in that it is bination with other dyes to z. B. brown or green shades not plioto- trop is. a. i kg acetate silk is used in the game i described way with 2o g des Dye 4-benzolazo-4'-nitro-2'-sulfo.diphe- nylamine colored. The yellow dyeing obtained also has good fastness properties.
