PATENTAMT.PATENT OFFICE.
Es wurde gefunden, daß man mittels der Diazoverbindung des p-Nitrobenzolazo-otoluidins auf der mit ß-Naphtol in gewöhnlicher Weise präparierten Faser rotbraune Färbungen und Drucke erhält, die sich durch hervorragende Echtheit auszeichnen.It has been found that by means of the diazo compound of p-nitrobenzolazo-otoluidine on the fiber prepared in the usual way with ß-naphtol receives reddish-brown colorations and prints, which can be seen through excellent authenticity.
Die Nuance der auf ß-Naphtol resultieren-. den Granatfarbe kommt dem alten Alizaringranat sehr nahe. Die erhaltene Farbe ist ίο nahezu ebenso echt, aber noch schoner als die mit Alizarin hergestellte.The nuance of the result- on ß-naphtol. the garnet color comes from the old alizarin garnet very close. The color obtained is almost as real, but even more beautiful than the one made with alizarin.
Außerdem hat das neue Granat die wertvolle Eigenschaft, sich mittels Hydrosulfits NF Höchst (Hydrosulfit-Formaldehyd) rein weiß ätzen zu lassen, was für die Technik von großem Wert ist.In addition, the new garnet has the valuable property of being hydrosulphite NF Höchst (hydrosulfite-formaldehyde) to be etched in pure white, something for the technology is of great value.
Gegenüber der Verwendung anderer Basen, wie a-Naphtylamin usw., bietet diejenige des p-Nitrobenzolazo-o-toluidine noch den Vorteil, daß man zu seiner Diazotierung kein Eis benötigt, da diese bei einer Temperatur von 15 bis 2O° ausgeführt werden kann.Compared to the use of other bases, such as a-naphthylamine etc., offers the one of p-nitrobenzolazo-o-toluidine still has the advantage that you do not have to diazotize it Ice is required as this can be done at a temperature of 15 to 20 °.

Diazotization is neutralized with 30 g of sodium acetate and adjusted to 1 liter with water.
Der Stoff oder das Garn wird mit ß-Naphtol in gewöhnlicher Weise präpariert, getrocknet, in vorstehender Diazolösung entwickelt, gewaschen und event, geseift.The fabric or the yarn is prepared with ß-naphtol in the usual way, dried, developed, washed and, if necessary, soaped in the above diazo solution.
Anwendet man anstatt ß-Naphtol eine Grundierung" mit a-Naphtol oder Gemischen von beiden, so erhält man ganz dunkle, volle Puce-Nuancen.If you use a instead of ß-naphtol Priming "with a-Naphtol or a mixture of both, you get very dark, full ones Puce nuances.
