Description

Puntätzverfahren Es` wurde gefunden, daß man Küpenfärbungen ohne Heranziehen der üblichen ätzenden Substanzen, wie beispielsweise Hydrosulfitpräparate, buntätzen Bann, wenn man sie mit einer Druckpaste bedruckt, die einerseits Alkalien, wie Alkalicarbonat, und Sulfonsäuren von organischen Ammoniumverbin-,dungen und anderseits Alkalisalze von Kupplungskomponenten enthalten, so daß .nach erfolgtem Drück Bunteffekte durch umnittelbar darauffolgendes Passieren durch eine Diazoverbindungerzeugt werden können. Die Alkalisalze von Kupplungskomponenten können auch durch Gemische von Kupplungskomponenten 'und Verbindungen, die auf Zusatz von Säuren in Diazoverbindungen übergeführt werde, wie Nitrosamine oder Diazoaminoverbindungen, ersetzt. werden. In diesem Falle werden Bunteffekte dadurch erzeugt, daß man nach erfolgtem Druck und Dampfpassage unmittelbar durch eine Säure passiert. Die folgenden Beispiele erläutern das neue Verfahren, das selbstverständlich noch mit anderen Verfahren kombiniert werden kann. Beispiel z Man bedruckt eine Färbung von Cibablau2 B (Schultz Farbstofftabellen Nr. 1314) mit folgender Ätzpaste: 55o g neutrale Stärketragant- verdickung, 5o g Kaliumcarbonat, 8o g eines Salzes des Anlagerungs- produktes von Benzylchloridsul- fonsäure an Dimethylanilin; 2o bis'3o g eines Alkalisalzes des Anilids der 2, 3-Oxynaphthoesäure, ` 30 g- einer 3o°/oigen Anthrachinon- ' paste, 23o bis 240 g Wasser, 30 g Türkischrotöl IOOo g. Man dämpft 5 Minuten im Mather-Platt und passiert unmittelbar in einer kalten Lösung, die pro Liter Wasser 2o g 4o°[aige Essigsäure und 17 g diazotiertes o-Nitranilin enthält; spült und seift kochend. Man erhält so scharlachrote Ätzungen auf blauem Grunde.Etching process It has been found that vat dyeings can be banished without using the usual caustic substances, such as hydrosulfite preparations, if they are printed with a printing paste that contains, on the one hand, alkalis, such as alkali carbonate, and sulfonic acids of organic ammonium compounds and, on the other hand, alkali salts of Contain coupling components, so that after pressing, colorful effects can be generated by subsequently passing through a diazo compound. The alkali salts of coupling components can also be replaced by mixtures of coupling components and compounds which are converted into diazo compounds on addition of acids, such as nitrosamines or diazoamino compounds. will. In this case, colorful effects are created by passing through an acid immediately after the pressure and steam have passed. The following examples explain the new process, which of course can be combined with other processes. Example z A color of Cibablau2 B (Schultz color table no.1314) is printed with the following etching paste: 55o g neutral starch carrier thickening, 5o g potassium carbonate, 8o g of a salt of the addition product of benzyl chloride sulfate fonsäure on dimethylaniline; 20 to 30 g of an alkali salt of anilide of 2, 3-oxynaphthoic acid, ` 30 g of a 30% anthraquinone 'paste, 23o to 240 g water, 30 g Turkish red oil IOOo g. It is steamed for 5 minutes in the Mather-Platt and immediately passed into a cold solution which contains 2o g 40 ° acetic acid and 17 g diazotized o-nitroaniline per liter of water; rinses and soap at the boil. This gives you scarlet etchings on a blue background.

Beispiele Man bedruckt eine in Cibablau 2 B (Schultz Farbstofftabellen Nr. 1314) erstellte Färbung mit folgender Druckpaste: 6o bis So g einer Mischung, bestehend aus einer äquiniolekularen Menge der Diazoaminoverbindung äus diazotiertem 4-Chlor-i-amino- 2-methylbenzol und i-Aminö- 5 - sulfon - 2 -benzolcarbonsäure und dem 2-Methyl-4-anisidid der 2, 3-Oxynaphthoesäure, ißo bis Zoo g Wasser, 30 g Türkischrotöl, 55o g neutrale Stärketragant- - verdickung; So g eines Salzes des Anlagerungs- produktes von Benzylchlorid- sitlfonsäure an Dimethylanilin, So g Kaliumcarbonat 1000 g: Man trocknet, dämpft 2 bis 5 Minuten im Mather-Platt, dann passiert man unmittelbar während-2o bis 3a Sekunden durch ein Bad, enthaltend bei 95 bis ioo° C. Hierauf wird gut gespült und kochend geseift. Man. erhält so Rottöne auf blauem Grunde.EXAMPLES A dye made in Ciba blue 2 B (Schultz color table no. 1314) is printed with the following printing paste: 6o to So g of a mixture consisting of an equiniolecular amount the diazoamino compound äus diazotized 4-chloro-i-amino- 2-methylbenzene and i-amino oil 5 - sulfone - 2 -benzenecarboxylic acid and the 2-methyl-4-anisidide of 2,3-oxynaphthoic acid, ißo to zoo g of water, 30 g Turkish red oil, 55o g neutral starch carrier - thickening; So g of a salt of the attachment product of benzyl chloride sulfonic acid on dimethylaniline, So g of potassium carbonate 1000 g: It is dried, steamed for 2 to 5 minutes in the Mather-Platt, then immediately passed through a bath containing -20 to 3 a seconds at 95 to 100 ° C. It is then rinsed well and soaped at the boil. Man. thus obtains red tones on a blue background.

Ähnlich verfährt man mit anderen Küp.enfarbstoffen, z. B. Indanthrenrot RK (Schultz Farbstofftabellen Nr. r258); Cibagelb G (.$,"chultz Nr. r323.), Cibägrau B (Schultz '@ 1335), Helindonorange R (Schultz Nr. 1349), Cibarot G (Schultz Nr. 1339) sowie die übrigen verschiedensten indigoiden bzw. thioindi.goiden Farbstoffe, wie z. B. 2, 2'-Thionaphthindigo oder Cibanongrün GC (S c h u 1 t z Farbstofftauellen -Nr. 1342).The procedure is similar with other Küp.enfarbstoffen such. B. Indanthrene red RK (Schultz Dye Tables No. r258); Ciba yellow G (. $, "Chultz No. r323.), Ciba gray B (Schultz '@ 1335), Helindonorange R (Schultz No. 1349), Cibarot G (Schultz No. 1339) as well as the other various indigoid or thioindigoid dyes, such as B. 2, 2'-thionaphthindigo or cibanon green GC (S c h u 1 t z dye tauellen -No. 1342).
