PATENTAMT.PATENT OFFICE.
Im Patent 157786, Kl. 22 a sind o-Oxymonoazofarbstoffe beschrieben worden, die beim Nachchromieren schwarze Farblacke von tadelloser Pottingechtheit zu liefern vermögen. Es sind dies die Farbstoffe, die aus ο -Amidophenolsulf osäuren und deren Derivaten einerseits und I · 5 - Dioxynaphtalin andererseits erhalten werden.In patent 157786, cl. 22a, o-oxymonoazo dyes are have been described, which are able to deliver black colored lacquers of impeccable potting fastness when chromium plating. These are the dyes that are made from ο -amidophenolsulfonic acids and their derivatives on the one hand and I · 5 - dioxynaphthalene on the other hand can be obtained.
Es hat sich nun weiter herausgestellt, daß ίο auch diejenigen Farbstoffe aus o-Amido-. phenolsulfosäuren und deren Derivaten, zu deren Herstellung an Stelle des genannten Dioxynaphtalins dessen Monosulfosäuren verwendet werden, beim Nachchromieren derartige hervorragend echte Farblacke zu liefern vermögen. Durch diese Echtheitseigenschaften unterscheiden sich die neuen Produkte vorteilhaft von den bisher bekannt gewordenen ο-Oxyazo farbstoff en aus isomeren Dioxynaphtalinsulfosäuren (vergl. z. B. die Patentschrift 131527 und die britische Patentschrift 11437/98).It has now been found that ίο also those dyes from o-amido-. phenolsulfonic acids and their derivatives, for their preparation in place of the above Dioxynaphthalene whose monosulphonic acids are used, such as those used in post-chrome plating able to deliver excellent real color lacquers. Through these authenticity properties the new products differ advantageously from those previously known ο-Oxyazo dyes from isomeric dioxynaphthalene sulfonic acids (See e.g. Patent 131527 and British Patent 11437/98).
Beispiel. 19kg o-Amidophenol-p-sulfosäure werden in gewöhnlicher Weise in die Diazoverbindung übergeführt und diese zu einer eiskalten Lösung von 26,5 kg des sauren Natronsalzes der 1 · 5 - Dioxynaphtalin - 3-sulfosäure (die z. B. durch Verschmelzen der 1:3: 5-Naphtalintrisulfosäure mit Ätzalkalien gewonnen werden kann) zugegeben.. Es wird sodann Natronlauge in geringem Überschuß zugefügt. Nach mehrstündigem Rühren ist die Farbstoffbildung vollendet. Die überschüssige Natronlauge wird durch Zugabe von Salzsäure abgestumpft, der Farbstoff ausgesalzen, filtriert, gepreßt und getrocknet. Er färbt Wolle in saurem Bade in blaustichig roten Tönen an. Beim Nachchromieren wird ein tiefes, pottingechtes Blauschwarz erhalten.Example. 19kg o-amidophenol-p-sulfonic acid are converted in the usual way into the diazo compound and this into a ice-cold solution of 26.5 kg of the acidic sodium salt of 1 · 5 - dioxynaphthalene - 3-sulfonic acid (e.g. obtained by fusing 1: 3: 5 naphthalene trisulfonic acid with caustic alkalis can be obtained) added. Sodium hydroxide solution is then added in a slight excess. After several hours Stirring the dye formation is complete. The excess caustic soda gets through Addition of hydrochloric acid blunted, the dye salted out, filtered, pressed and dried. He dyes wool in an acid bath in bluish red tones. When re-chrome plating a deep, potting-fast blue-black is obtained.
Die Darstellung der anderen nach dem vorliegenden Verfahren erhältlichen Farbstoffe geschieht in vollkommen analoger Weise.The representation of the other dyes obtainable by the present process happens in a completely analogous way.
In folgender Tabelle sind die Nuancen einer Anzahl der nach dem vorliegenden Verfahren erhältlichen Produkte angeführt.In the table below are the nuances of a number of those made by the present process available products are listed.
