Description

Verfahren zur Herstellung gefärbter Lacke Es ist bekannt, daß zur Herstellung von lichtecht gefärbten Lacken (welche auf Cellulose- oder Phenolaldehydbasis hergestellt sein können) Aminoanthrachinone verwendet werden können.Process for the production of colored paints It is known that for Production of lightfast colored paints (those based on cellulose or phenol aldehyde can be prepared) Aminoanthraquinones can be used.

Es wurde nun die wichtige Beobachtung gemacht, daß man außerordentlich lichtechte, transparente gelbe bis blaurot gefärbte Lacke herstellen kann, wenn man diese mit solchen Farbstoffen färbt, welche- der allgemeinen Formel entsprechen, in welcher R,. den aromatischen Kern einer negativ substituierten, unsulfierten Diazoverbindung, R, den aromatischen Kern eines in 4-Stellung zur -Gruppe kuppelnden Amins und R, -und R4 Wasserstoff bzw. Alkyl-, Aralkyl- oder Arylreste bedeuten.The important observation has now been made that extremely lightfast, transparent yellow to blue-red colored lacquers can be produced if these are colored with such dyes which correspond to the general formula correspond, in which R ,. the aromatic nucleus of a negatively substituted, unsulfated diazo compound, R, the aromatic nucleus of one in the 4-position to the -Group coupling amine and R 1 and R 4 are hydrogen or alkyl, aralkyl or aryl radicals.

Beispiel i Man löst 4 bis 5 Teile des durch Vereinigen von diazotiertem p-Nitranilin und Kresidin erhältlichen Farbstoffes in iooo Teilen fertigem Zaponlack. Die so erhaltene Flüssigkeit, in dünner Schicht auf die verschiedensten Unterlagen (Metall, Glas, Leder, Holz, Celluloid. Seide usw.) aufgebracht, hinterläßt beim Eintrocknen einen transparenten Überzug, dessen intensiv scharlachrote Farbe vorzüglich lichtecht ist. Durch Einverleibung geeigneter Zusätze, wie z. B. Zinkoxyd oder Bariumsulfat in fein vermahlenem Zustande oder noch von Wachsen, kann der transparente Lack, je nach den zugefügten Mengen, mehr oder weniger vollkommen in einen Matt- oder Decklack übergeführt werden.Example i 4 to 5 parts of the diazotized by combining p-Nitraniline and cresidine available dye in 10000 parts of finished zapon varnish. The liquid obtained in this way, in a thin layer on various substrates (Metal, glass, leather, wood, celluloid, silk, etc.) applied, leaves behind Drying a transparent coating, its intense scarlet color is excellent is lightfast. By incorporating suitable additives, such as. B. zinc oxide or barium sulfate in finely ground condition or still waxed, the transparent varnish, depending on the added quantities, more or less completely in a matt or Top coat to be transferred.

Beispiel e Man versetzt, gegebenenfalls unter Zugabe weiterer Lösungsmittel und der üblichen Weichmachungs- bzw. Plastifizierungsmittel, eine Nitrocelluloselösung mit einer acetonischen Lösung von 4-Nitro-_l.'-aminoazobenzol. Der so erhaltene Lack wird zur Herstellung von orangeroten Überzügen von vorzüglicher Lichtechtheit verwendet.Example e The mixture is added, if appropriate with the addition of further solvents and the usual plasticizers, a nitrocellulose solution with an acetone solution of 4-nitro-_l .'-aminoazobenzene. The thus obtained Lacquer is used to produce orange-red coatings of excellent lightfastness used.

Ähnliche Resultate erhält man mit Lacken aus Acetylcellulose oder aus PhenoWdehydkondensationsprodukten. Im letzteren. Fall widerstehen die Färbungen den verschiedenen Härtungsverfahren.Similar results are obtained with lacquers made from acetyl cellulose or from PhenoWdehyde condensation products. In the latter. Fall resist the stains the different hardening processes.

Gelbe Lacke erhält man mit Produkten wie 2, 5-Dichlor-4'-aminoazobenzol bzw. 2, 5-Dichlor-q.'-amino-3'-methylazobenzol, orangefärbende mit 3-1\Titro-4'=aminoazobenzol, scharlachrote mit q.-Nitro-4' aMino-2'-aCetylaminoazobenzol, blaurote mit 4-Nitro-2-methoxy-4.'-dialkylam.inoazobenzol usw. Gut geeignet sind ebenfalls die Azofarbstoffe aus unsulfierten negativ substituierten Diazoverbindungen und Diphenylaminen, ferner aus Benzyl- bzw. Athylbenzyl- bzw. Dibenzylanilin.Yellow paints are obtained with products such as 2,5-dichloro-4'-aminoazobenzene or 2, 5-dichloro-q .'-amino-3'-methylazobenzene, orange colored with 3-1 \ Titro-4 '= aminoazobenzene, scarlet with q.-nitro-4'aMino-2'-aCetylaminoazobenzene, blue-red with 4-nitro-2-methoxy-4 .'-dialkylam.inoazobenzene etc. The azo dyes from unsulfated negatively substituted ones are also very suitable Diazo compounds and diphenylamines, also from benzyl or ethylbenzyl or Dibenzylaniline.
