Description

Verfahren zum Färben künstlicher Seide aus Celluloseestern oder -äthern bzw. ihren Umwandlungsprodukten Zusatz zum Patent 433z36 Durch das Hauptpatent 433 236 ist ein Verfahren zum Färben von künstlicher Seide aus Celluloseestern bzw. -äthern geschützt. Es besteht darin, daß man hierzu die o-Sulfosäuren der a-Aminoanthrachinone, ihre Substitwtion;sprodukte und Derivate verwendet.A method of dyeing artificial silk or Celluloseestern -äthern or their transformation products addition to Patent 433z36 through the main patent 433,236 a process for dyeing is protected from artificial silk or Celluloseestern -äthern. It consists in using the o-sulfonic acids of the a-aminoanthraquinones, their substitution products and derivatives for this purpose.

Es wurde nun gefunden. daß man hierzu auch die o-Sttlfosäuren der ß-_,#minoanthrachinone, ihre Substitutionsprodukte und Derivate verwenden kann.It has now been found. that this also includes the o-sttlfosäuren ß -_, # minoanthraquinones, their substitution products and derivatives can use.

Mit Rücksicht auf das unterschiedliche Verhalten der Acetatseide gegen sulfierte Aminoanthrachinone war diese Erweiterung des Gebietes nicht ohne weiteres vorauszusehen.With regard to the different behavior of the acetate silk against sulfated aminoanthraquinones, this expansion of the area was not straightforward to foresee.

Beispiel. o,6 Gewichtsteile der a-AminoanthrachinOn-3-sulfosäure werden in einem Liter Wasser heiß gelöst. Man färbt im Flottenverhältnis r : 2o mit oder- ohne Zusatz von Salzen bei 70° während % Stunde. Der Farbstoff zieht auf Acetatseide in klaren, gelben Tönen.Example. 0.6 parts by weight of the α-aminoanthraquinOn-3-sulfonic acid dissolved in a liter of hot water. One dyes in the liquor ratio r: 2o with or- without addition of salts at 70 ° for% hour. The dye draws on acetate silk in clear, yellow tones.
