Description

Herstellung blaugrüner Farblacke. In der Patentschrift 224442 ist ein Verfahren zur Herstellung blaugrüner Farblacke beschrieben, welches darin besteht, daß man die durch Behandeln von in 8-Stellung nicht substituierten Sulfosäuren des i, 2-Naphthylendiamins mit Ferrisalzen erhaltenen Farbstoffe nach den üblichen Methoden in Farblacke überführt.Production of blue-green colored lakes. In patent specification 224442 is a process for the production of blue-green colored lakes described, which consists in that one des by treating unsubstituted in the 8-position sulfonic acids i, 2-Naphthylenediamines obtained with ferric salts by the usual methods converted into colored lacquers.

Es wurde nun gefunden, daß sich auch die durch Behandeln von in 8-Stellung durch Halogene substituierten Sulfosäuren des i, 2-Naphthylendiamins mit Ferrisalzen erhaltenen Farbstoffe zur Herstellung solcher blaugrüner Farblacke sehr gut eignen.It has now been found that by treating in the 8-position sulfonic acids of i, 2-naphthylenediamine substituted by halogens with ferric salts The dyes obtained are very suitable for the production of such blue-green lakes.

Die Farblacke weisen eine klarere, blauere Nuance auf als diejenigen der Patentschrift 22q442 und besitzen besonders gute Echtheitseigenschaften.The color lakes have a clearer, bluer shade than those the patent specification 22q442 and have particularly good fastness properties.

B e i s p i e 1 : 5 kg schwefelsaure Tonerde i8prozentig, gelöst in 5o 1 Wasser, 30 kg Schwerspat, 2 kg calcinierte Soda, gelöst in 2o 1 Wasser. 3 kg Farbstoff aus i, 2-Naphthylendiamin-8-chlor-5-sulfosäure und Eisenchlorid, gelöst in ioo 1 Wasser, 9 kg kristallisiertes Chlorbarium, gelöst in 9o 1 Wasser, werden zusammengegeben, der entstandene Farblack abgepreßt und entweder so als Paste oder nach dem Trocknen verwendet.Example 1: 5 kg 8 percent sulfuric alumina, dissolved in 5o 1 water, 30 kg barite, 2 kg calcined soda, dissolved in 2o 1 water. 3 kg of dye from i, 2-naphthylenediamine-8-chloro-5-sulfonic acid and iron chloride, dissolved in 100 1 of water, 9 kg of crystallized chlorobarium, dissolved in 90 1 of water, are combined, the resulting colored varnish is pressed off and either as a paste or used after drying.
