Description
Färbebäder und Druckpasten Es wurde gefunden, daß man'Gebilde aus Polyestern in ausgezeichneter Weise färben oder bedrucken kann, wenn man Färbebäder oder Druckpasten verwendet, die als Farbstoffe einen Gehalt an Anthrachinonderivaten der allgemeinen-Formel aufweisen, in der R1 einen gegebenenfalls substituierten aromatischen oder heterocyclischen Rest und R2 ein Wasserstoff-, Chlor-oder Bromatom bedeuten.Dye baths and printing pastes It has been found that one'Gebilde made of polyesters can be dyed or printed in an excellent manner if dyebaths or printing pastes are used which contain anthraquinone derivatives of the general formula as dyes have, in which R1 is an optionally substituted aromatic or heterocyclic radical and R2 is a hydrogen, chlorine or bromine atom.
In der allgemeinen Formel Ikann R1 einen aromatischen oder heterocyclischen Rest, wie einen Phenyl-, Naphthyl-(1)-oder Thienyl-(2)-rest bedeuten, wobei diese Reste noch-Substituenten enthalten können. Als Substituenten seien beispielsweise Halogenatome, wie Chlor- oder Bromatome, Hydroxygruppen, Aminogruppen, Alkylgruppen, wie Methyl-, Äthyl-, Propyl-, Butylgruppen, Alkoxygruppen, wie Methoxy-, Äthoxygruppen, Mercaptogruppen, Alkylmercaptogruppen, wie Methylmercaptogruppen oder Nitrogruppen genannt. Der Rest R1 kann zoBo folgende Bedeutung haben: Phenyl, 4-, 3- oder 2-Methylphenyl, 4-Iso-propylphenyl, 4-, 3- oder 2-Methoxyphenyl, 4-Chlorphenyl, 2,4-Dichlorphenyl, 2-Methoxy-4-methylphenyl, 2-Methoxy-5-methylphenyl, 4-Aminophenyl, 4-Nitrophenyl, 2-Hydroxyphenyl9 4-Methylmercaptophenyl, _ Naphthyl-(1) und Thienyl-(2)o Farbstoffe mit einem aromatischen Ri-Rest sind bevorzugt.In the general formula, R1 can be an aromatic or heterocyclic one Radical, such as a phenyl, naphthyl (1) or thienyl (2) radical, these Residues may still contain substituents. Examples of substituents are Halogen atoms, such as chlorine or bromine atoms, hydroxyl groups, amino groups, alkyl groups, such as methyl, ethyl, propyl, butyl groups, alkoxy groups such as methoxy, ethoxy groups, Mercapto groups, alkyl mercapto groups such as methyl mercapto groups or Called nitro groups. The radical R1 can have the following meaning: phenyl, 4-, 3- or 2-methylphenyl, 4-iso-propylphenyl, 4-, 3- or 2-methoxyphenyl, 4-chlorophenyl, 2,4-dichlorophenyl, 2-methoxy-4-methylphenyl, 2-methoxy-5-methylphenyl, 4-aminophenyl, 4-nitrophenyl, 2-hydroxyphenyl9 4-methylmercaptophenyl, _ naphthyl- (1) and thienyl- (2) o Dyes with an aromatic Ri radical are preferred.
Die Farbstoffe der Formel I sind neu. Sie können zoBo erhalten wer- . den, wenn man 1,2-Diaminoanthrachinon, 1,2-Diamino-3-chloranthrachinon oder 1,2-Diamino-3-bromanthrachinon mit Säuren der allgemeinen e Formel Ri-CH-CH-COOH oder den entsprechenden Säurehalogeniden, Aldehyden, Orthoestern oder Acetalen umsetzt. Beispielsweise erhält man den Farbstoff der Formel indem man 1,2-Diamino-3-bromanthraehinon mit 4-Methylzimtsäurechlorid bei erhöhter Temperatur in Nitrobenzol umsetzt.The dyes of the formula I are new. They can be obtained from zoBo. the, when 1,2-diaminoanthraquinone, 1,2-diamino-3-chloroanthraquinone or 1,2-diamino-3-bromoanthraquinone with acids of the general formula Ri-e CH-CH-COOH, or the corresponding acid halides, aldehydes, Orthoestern or acetals. For example, the dye of the formula is obtained by reacting 1,2-diamino-3-bromanthraehinone with 4-methylcinnamic acid chloride at an elevated temperature in nitrobenzene.
Gebilde aus Polyestern sind beispielsweise Folien, Filme oder Textilgut, wie Fasern, Fäden, Flocken, Gewebe und Gewirke aus diesen Stoffen. Als Polyester seien Z.Ba die aus Terephthalsäure und Äthylenglykol oder CC-Dimethyloleyclohexan erhältlichen Produkte genannt Zum Färben verwendet man Färbeflotten, die die Farbstoffe vorteilhaft in fein verteilter Form enthalten. Mit diesen Flotten kann man Textilgut aus Polyestern zoBo bei Temperaturen zwischen 95 bis 100°C unter gewöhnlichem Druck oder'bei Temperaturen über 100°C nach dem HT-Verfahren oder dem Thermosolverfahren färben. Will man bei Temperaturen um 100°C kräftige Färbungen erhalten, so ist es zweckmäßig, den Färbeflotten Färbebeschleuniger, sogenannte "Carrier", zuzusetzen.Structures made of polyesters are, for example, foils, films or textiles, such as fibers, threads, flakes, woven and knitted fabrics made from these fabrics. As polyester be e.g. those from terephthalic acid and ethylene glycol or CC-Dimethyloleyclohexan available products called For dyeing one uses dye liquors which contain the dyes advantageously contained in finely divided form. With these fleets you can Textile goods made of polyester zoBo at temperatures between 95 to 100 ° C under normal pressure oder'at temperatures above 100 ° C according to the HT process or the thermosol process to dye. If you want to get strong colors at temperatures around 100 ° C, then it is It is expedient to add dye accelerators, so-called "carriers", to the dye liquors.
Zum Bedrucken von Textilgut aus Polyestern verwendet man Druckpasten, die neben den üblichen Verdickungsmitteln und Druckhilfsmitteln die genannten Farbstoffe in fein verteilter Form enthalten. Zweckmäßig gibt man auch den Druckpasten Färbebeschleuniger zu. Nach dem Be-9-drucken wird das Gutwie üblich gedämpft und fertiggestellt.Printing pastes are used to print polyester fabrics. the dyes mentioned in addition to the customary thickeners and printing auxiliaries contained in finely divided form. Dye accelerators are also expediently added to the printing pastes to. After printing, the item is steamed and finished as usual.
Mit den erfindungsgemäßen Farbstoffen erhält man Färbungen und Drucke,
die sieh durch gute Wasch-, Licht-, Reib- und thermische Echtheitseigenschaften
auszeichnen und solche Färbungen auf Polyester in der Farbstärke erheblich übertreffen,
die mit den in der belgischen Patentschrift 661 414 beschriebenen Farbstoffen erhalten
werden. Der Farbton reicht vom grünstichigen Gelb bis zum Orange. Die in den Beispielen
gngegebenen Teile sind Gewichtsteile. Beispiel 1
100 Teile Polyäthylenglykolterephthalatgewebe
werden in einem Färbebad, das aus 5000 Teilen Wasser, 5 Teilen einer durch Umsetzung
von 1 Mol Spermölalkohol mit 80 Mol Äthylenoxyd und nachfolgender Sulfierung erhältlichen
Verbindung und 1 Teil des feinverteilten Farbstoffs der-Formel I, in der R1 einen
Phenylrest und R2 ein Chloratom bedeuten, besteht, 90 Minuten bei 135°C behandelt.
Man erhält eine sehr farbstarke
gelbe Färbung mit guten bis sehr
guten Echtheitseigenschaften Ähnliche grünstichig gelbe bis orange Färbungen werden
erhalten, wenn man anstelle des genannten Farbstoffs solche Farbstoffe der Formel
I verwendet, in der R1 und R2 die in der folgenden Tabelle bezeichneten Substituenten
enthalten
Liegt der Farbstoff in fein verteilter Form vor, so kann die im ersten Abschnitt dieses Beispiels beschriebene Verküpung unterbleiben.If the dye is in finely divided form, the first The linkage described in the section of this example.
