Gegenstand des Patentes 1 155 754 ist ein Verfahren zum Färben und Bedrucken von geformten Gebilden, wie Fasern, Geweben oder Folien, aus linearen aromatischen Polyestern, insbesondere PoIyäthylenterephthalaten, oder Polyamiden, wobei man die genannten Gebilde mit wäßrigen Dispersionen von sulfonsäure- und carbonsäuregruppenfreien Farbstoffen der nachstehenden allgemeinen FormelThe subject of patent 1,155,754 is a process for dyeing and printing molded Formed, such as fibers, fabrics or films, from linear aromatic polyesters, in particular polyethylene terephthalates, or polyamides, the structures mentioned being mixed with aqueous dispersions of dyes free of sulfonic acid and carboxylic acid groups the general formula below

in welcher die Gruppe R — CO — in m- oder p-Stellung zur Azogruppe steht, R ein Wasserstorfatom oder einen niedermolekularen Alkylrest bedeutet, der Benzolkern A noch durch ein Chloratom substituiert sein kann und B den Rest eines aromatischen oder heterocyclischen o-Oxycarbonsäurearylides darstellt, behandelt.in which the group R - CO - in m- or p-position to the azo group, R a hydrogen atom or a low molecular weight alkyl radical, the benzene nucleus A also by a chlorine atom can be substituted and B is the radical of an aromatic or heterocyclic o-oxycarboxylic acid arylide represents, treated.
In weiterer Ausgestaltung dieses Erfindungsgedankens wurde nun gefunden, daß man an Stelle der dort genannten Farbstoffe deren Oxime in gleicher Weise zum Färben und Bedrucken der geformten Gebilde aus linearen aromatischen Polyestern, insbesondere Polyäthylenterephthalaten, oder aus Polyamiden verwenden kann.In a further embodiment of this inventive concept, it has now been found that instead of of the dyes mentioned there, their oximes in the same way for dyeing and printing the shaped ones Structures of linear aromatic polyesters, in particular polyethylene terephthalates, or made of polyamides can be used.
Im einzelnen kann dabei so verfahren werden, daß man den Färbebädern bzw. Druckpasten die bereits in Substanz hergestellten Oxime der genannten Farbstoffe zusetzt oder daß man die carbonylgruppenhaltigen Farbstoffe zusammen mit Hydroxylamin, zweckmäßig in Form eines Salzes, den Färbebädern bzw. Druckpasten zusetzt und auf diese Weise die Oxime der Farbstoffe erst während des Färbens oder Drückens erzeugt. Schließlich kann auch so verfahren werden, daß man Färbungen oder Drucke auf den genannten geformten Gebilden, die mit den noch nicht in die entsprechenden Oxime übergeführten carbonylgruppenhaltigen Farbstoffen hergestellt worden sind, mit der wäßrigen Lösung eines Hydroxylaminsalzes bei höheren Temperaturen, beispielsweise bei 100°C, nachbehandelt.In detail, the procedure can be such that the dye baths or printing pastes are already Oximes of the dyes mentioned, which are prepared in bulk, are added or the carbonyl-containing ones are added Dyes together with hydroxylamine, expediently in the form of a salt, in the dyebaths or printing pastes added and in this way the oximes of the dyes only during dyeing or Pressing generated. Finally, it is also possible to proceed in such a way that dyeings or prints are applied to the called formed structures, which have not yet been converted into the corresponding oximes with the carbonyl group-containing dyes have been prepared with the aqueous solution of a hydroxylamine salt aftertreated at higher temperatures, for example at 100 ° C.
Durch die Verwendung der genannten Oxime kann man eine erhebliche Farbvertiefung bei der Her-Anmelder: By using the oximes mentioned, you can achieve a considerable deepening of the color in the case of the applicant:

Stellung von Färbungen und Drucken auf den geformten Gebilden aus den genannten Materialien erzielen. So kann man auf diese Weise erheblich blaustichigere Nuancen erreichen. Zum Teil übertreffen die gemäß dem Verfahren der vorliegenden Erfindung zur Anwendung gelangenden Oxime die carbonylgruppenhaltigen Ausgangsfarbstoffe auch im Ziehvermögen und bzw. oder in den Echtheiten.Positioning of dyeings and prints on the shaped structures made of the materials mentioned achieve. In this way, you can achieve significantly more bluish nuances. Partly outperform the oximes used in accordance with the method of the present invention starting dyes containing carbonyl groups also in the drawability and / or in the fastness properties.
