  . Verfahren zum Färben mittels indigoider Farbstoffe, sowie   Herstellung leicht verküpbarer   Produkte aus indigoiden Farbstoffen bzw. von Reduktionsmitteln für die Küpenführung derselben. 



   In der Stammpatentschrift Nr. 53018 wurde eine Verbesserung in der Küpenführung bei indigoiden Farbstoffen beschrieben, welche auf der katalytischen Wirkung des Anthrachinons und seiner Derivate beruht. 



   In der weiteren Verfolgung dieses Erfindungsgegenstandes wurde gefunden, dass an die Stelle des Anthrachinons oder seiner Derivate eine grosse Zahl anderer reduzierbarer und wieder oxydierbarer Körper treten kann. Es wurde ermittelt, dass auch die Chinone der   Benzol-und Naphtalinreihe   und die Chinone höherer Kohlenwasserstoffe in ähnlicher 
 EMI1.1 
 chinon usw. sehr gute Resultate erzielt. 



   Hiemit ist aber die Zahl der an Stelle des Anthrachinons zu setzenden Reduktionsvermittler noch lange nicht erschöpft. Es wurde gefunden, dass eine grosse zahl anders zusammengesetzter Körper im gleichen Sinne wie das Anthrachinon anwendbar ist, wenn diesen Substanzen die Eigenschaft innewohnt, schneller reduzierbar zu sein als wie die angewendeten Küpenfarbstoffe und wenn sie im   LeLkozustat'lte   wieder rascher   oxydiem. u

 werden. Gute   Resultate   werden ferner erzielt mit Nitrosonaphtolen und deren   Suifosauron,   Indophenolen und deren Sulfosäuren, ferner Isatin, Indigosulfosäure, Indigorubin, gewissen Triphenylmethanfarbstoffen, wie z. B. Patentblau, Setopalin und dgl.

  . Process for dyeing by means of indigoid dyes, as well as production of easily vettable products from indigoid dyes or reducing agents for the vat management of the same.



   In the parent patent specification No. 53018, an improvement in the vat management for indigoid dyes was described, which is based on the catalytic effect of the anthraquinone and its derivatives.



   In the further pursuit of this subject matter of the invention it was found that a large number of other reducible and reoxidizable bodies can take the place of the anthraquinone or its derivatives. It has been determined that the quinones of the benzene and naphthalene series and the quinones of higher hydrocarbons are similar

 chinone etc. gives very good results.



   This does not, however, exhaust the number of reducing agents to be substituted for the anthraquinone. It has been found that a large number of differently composed bodies can be used in the same way as anthraquinone if these substances have the inherent property of being more rapidly reducible than the vat dyes used and if they are oxidized more quickly in the body. u

 will. Good results are also achieved with nitrosonaphthols and their suifosauron, indophenols and their sulfonic acids, isatin, indigosulfonic acid, indigorubine, certain triphenylmethane dyes, such as. B. Patentblau, Setopalin and the like.

PATENT-ANSPRUCH : Abänderung des in der Stammpatentschnft Nr. 53018 beschriebenen Verfahrens zum Färben mittels indigoider Farbstoffe, sowie Herstellung leicht verküpbarer Produkte aus indigoiden Farbstoffen bzw. von Reduktionsmitteln für die Küpenführung derselben, dadurch gekennzeichnet, dass man an Stelle von Anthrachinon und seinen Derivaten andere Körper, wie z. B. Chinone der Benzol-, Naphtalin- und Phenanthrenreihe und deren Derivate, Nitrosonaphtole, Indophenole, Körper der Indigoreihe, Triphenylmethanfarbstoffe usw. verwendet, die sich leichter reduzieren lassen und andererseits von ihrer Leukostufe aus wieder leichter oxydierbar sind als die angewendeten Küpenfarbstoffe, so dass sie als Wasserstoffüberträger wirken. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Modification of the process described in the parent patent no. 53018 for dyeing by means of indigoid dyes, as well as the production of easily vettable products from indigoid dyes or reducing agents for the vat management of the same, characterized in that, instead of anthraquinone and its derivatives, other bodies, such as e.g. . B. quinones of the benzene, naphthalene and phenanthrene series and their derivatives, nitrosonaphthols, indophenols, bodies of the indigo series, triphenylmethane dyes, etc. are used, which are easier to reduce and on the other hand are more easily oxidized from their leuco level than the vat dyes used, so that they act as hydrogen carriers. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
