Description

Verfahren zur Herstellung echter Färbungen und Drucke Normalerweise werden in der Eisfarbentechnik rote Farbtöne durch Kuppeln von Diazoverbindungen mit 2-Oxynaphthalin oder 2, 3-Oxynaphthoesäurearylamiden auf der Faser hergestellt.Process for making true dyeings and prints Usually In the ice color technique, red hues are created by coupling diazo compounds made with 2-oxynaphthalene or 2, 3-oxynaphthoic acid arylamides on the fiber.

Bekannt und technisch in Anwendung ist auch die Erzeugung von bordoroten Tönen auf Cellulosefasern aus 4, 4'-Diacetoacetylamino-3, 3'-dimethyldiphenyl und der Diazoverbindung aus 4-Amino-4'-nitro-2, 5-dimethoxy-i, i'-azobenzol sowie von roten Tönen aus 4, 4'-Diacetoacetylamino-3, 3'-dimethyldiphenyl und der Diazoverbindung aus 4-Amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzol.The production of bordeaux is also known and technically used Tones on cellulose fibers from 4,4'-diacetoacetylamino-3, 3'-dimethyldiphenyl and the diazo compound from 4-amino-4'-nitro-2, 5-dimethoxy-i, i'-azobenzene and from red tones from 4,4'-diacetoacetylamino-3, 3'-dimethyldiphenyl and the diazo compound from 4-amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzene.

Diese unter Verwendung von 4, 4'-Diacetoacetylamino-3, 3'-dimethyldiphenyl als Azokomponente erhältlichen Färbungen und Drucke besitzen aber nur mäßige Lichtechtheiten.This using 4, 4'-diacetoacetylamino-3, 3'-dimethyldiphenyl However, dyeings and prints available as azo component have only moderate lightfastnesses.

Es wurde nun gefunden, daß man Färbungen und Drucke von erheblich höherer Klarheit und Lichtechtheit erhält, wenn man die Diazoverbindung aus 4-Arnino-4'-nitro-2, 5-dimethoxy-i, i'-azobenzol und/ oder aus 4-Amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzolmit i-Acetoacetylamino-2, 5-dimethoxy-4-chlor-Benzol auf der Faser vereinigt. Neben diesen lichtechten Rot- und Bordotönen lassen sich im Zeugdruck durch Aufdruck von diazotierten Substitutionsprodukten des Anilins lichtechte Gelbtöne und unter Mitverwendung von Leukoschwefelsäureestern blauer Küpenfarbstoffe, die gleichzeitig oder nachträglich zum Küpenfarbstoff oxydiert werden, weitere Effekte erzielen.It has now been found that dyeings and prints can be significantly reduced higher clarity and lightfastness is obtained if the diazo compound is obtained from 4-amino-4'-nitro-2, 5-dimethoxy-i, i'-azobenzene and / or from 4-amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzene with i-Acetoacetylamino-2,5-dimethoxy-4-chlorobenzene combined on the fiber. Next to These lightfast red and bordeaux tones can be printed on by imprinting diazotized substitution products of aniline, lightfast yellow tones and with use of leuco-sulfuric acid esters of blue vat dyes, simultaneously or subsequently are oxidized to the vat dye, achieve further effects.

Beispiel Baumwollgewebe wird auf dem Foulard mit nachstehender Grundierungslösung imprägniert, abgequetscht und getrocknet.Example cotton fabric is placed on the padder with the following primer solution impregnated, squeezed and dried.

14,19 i-Acetoacetylamino-2, 5-dimethoxy-4-chlorbenzol werden mit 2o ccm Natrontürkischrotöl 5o°/oig und 7 ccm Natronlauge 38° B6 angeteigt, mit kochendem Wasser übergossen und gelöst und mit etwa 50° warmem Wasser auf 11 eingestellt.14.1 9 i-Acetoacetylamino-2, 5-dimethoxy-4-chlorobenzene are made into a paste with 2o ccm sodium turkish red oil 5o% and 7 ccm caustic soda 38 ° B6, poured boiling water over them and dissolved and with about 50 ° warm water to 1 1 set.

Die getrocknete Ware wird mit einer Druckfarbe bedruckt, die q.o g des DiazoniumchlorzinkdopFelsalzes aus 4-Amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzol, mit Aluminiumsulfat und Natriumsulfat auf einen Basengehalt von 2o °/p eingestellt, gelöst in Wasser und 500 g Stärke-Tragantverdickung auf i kg Druckfarbe enthält.The dried goods are printed with a printing ink, the qo g of the DiazoniumchlorzinkdopFelsalzes from 4-amino-3'-nitro-2, 5-dimethoxy-i, i'-azobenzene, adjusted with aluminum sulfate and sodium sulfate to a base content of 20 ° / p , dissolved in water and contains 500 g of starch-tragacanth thickener on 1 kg of printing ink.

Man trocknet, spült und seift in der üblichen Weise und erhält ein lebhaftes Scharlachrot von guter Lichtechtheit.It is dried, rinsed and soaped in the usual way and received lively scarlet red with good lightfastness.

Ersetzt man die oben angewandte Diazoverbindung durch ein Diazoniumsalz aus 4.-Amino-q.'-nitro-2, 5-dimethoxy-i, i'-azobenzol, so erhält man ein klares blaustichiges Bordo. Verwendet man Gemische der beiden genannten Diazoniumverbindungen, so erhält man ebenfalls klare Farbtöne, die im Farbton zwischen denen der beiden Mischkomponenten liegen.If the diazo compound used above is replaced by a diazonium salt from 4.-Amino-q .'-nitro-2, 5-dimethoxy-i, i'-azobenzene, a clear one is obtained bluish bordo. If mixtures of the two diazonium compounds mentioned are used, in this way one also obtains clear color tones, the color tone between those of the two Mixing components lie.
