Description

Verfahren zum Färben und Bedrucken von Celluloseestern und -äthern Es wurde gefunden, daß man Cellulos.eester und -äther in vorzüglicher Weise färben und bedrucken kann, wenn man hierbei Monoazofarbstoffe, die durch Kuppeln von diazotierten aromatischen Verbindungen mit Phenol oder Phenolderivaten, deren Parastellung zur Hydroxylgruppe unbesetzt ist und die außer Alkylgruppen keine weiteren Substituenten enthalten, erhalten werden, verwendet. Die erhaltenen Färbungen zeichnen sich durch hervorragende Lichtechtheit und sonstige sehr gute Echtheitseigenschaften aus. Außerdem haben die Färbungen den Vorteil, daß sie nicht phototrop sind.Process for dyeing and printing cellulose esters and ethers It has been found that cellulose esters and ethers can be dyed in an excellent manner and can be printed if one uses monoazo dyes that are diazotized by coupling aromatic compounds with phenol or phenol derivatives, their para position to Hydroxyl group is unoccupied and apart from alkyl groups no further substituents contain, are obtained, used. The colorations obtained are distinguished excellent lightfastness and other very good fastness properties. aside from that the colorations have the advantage that they are not phototropic.

Die Eigenschaften der verwendeten Farbstoffe können noch verbessert werden, wenn man sie mit Halogenallkylen, Säurechloriden usw. nachbehandelt.The properties of the dyes used can still be improved if they are aftertreated with halogen alkyls, acid chlorides, etc.

Beispiel i Acetatseide wird in der üblichen Weise mit dem durch Kuppeln von diazotiertem Monoacetyl-p-phenylendiamin mit o-Kresol erhaltenen Farbstoff i Stunde lang bei 6o bis 8o° gefärbt. Man erhält eine gelbe, nicht phototrope Färbung von hervorragender Lichtechtheit. Ähnliche Färbungen erhält man mit anderen Monoazofarbstoffen, die sich von anderen Phenolen mit freier Parastellung, z. B. m-Kresol usw., ableiten. Beispiel z Man färbt Acetatseide in der üblic'he;n Weise mit dem mit Chloräthyl behandelten Farbstoff aus diazotiertem Anilin und Phenol. Man erhält eine gelbe Färbung von ausgezeichneten Echtheitseigenschaften.Example i Acetate silk is made in the usual manner with the coupling dye obtained from diazotized monoacetyl-p-phenylenediamine with o-cresol i Stained at 6o to 8o ° for 1 hour. A yellow, non-photochromic coloration is obtained of excellent lightfastness. Similar colorations are obtained with other monoazo dyes, which differ from other phenols with a free para position, e.g. B. m-cresol, etc., derive. Example z Acetate silk is dyed in the usual way with that of chloroethyl treated diazotized aniline and phenol dye. A yellow one is obtained Coloring with excellent fastness properties.
