Description

Verfahren zum Färben von Pelzen, Haaren u. dgl. In der Patentschrift 103505 wird unter anderem das 4-Nitro-2-amino-i-oxybenzol zum Färben von Pelzen oder Haaren vorgeschlagen. Es wurde nun gefunden, :daß sich das isomere 5-Nitro-2-amino-.i-oxybenzol und seine Kernsubstitutionsprodukte hiervon vorteilhaft bezüglich Ton und Stärke der Färbung unterscheiden.Process for dyeing fur, hair and the like in the patent 103505 is among other things the 4-nitro-2-amino-i-oxybenzene for dyeing fur or hair suggested. It has now been found that: the isomeric 5-nitro-2-amino-.i-oxybenzene and its core substitution products thereof advantageous in terms of clay and starch differ in color.

Beim Färben verfährt man in der üblichen Weise, indem man die genannten Verbindungen zusammen mit einem Oxydationsmittel auf das ungeibeizte oder mit Metallbeizen behandelte Material einwirken läßt. Die Färbungen zeichnen sich durch hervorragende Lichtechtheit aus.When dyeing one proceeds in the usual way by doing the mentioned Compounds together with an oxidizing agent on the unpickled or with metal pickling treated material can act. The colorations are excellent Lightfastness.

Beispiel. In ein Färbebad, enthaltend im Liter 2 g 5-Nitro-2-amino-i-oxybenzol, 2 g Ammoniak, 25prozentig, und 30 g Wasserstoffsuperoxyd, 3prozentig, bringt man das gut gereinigte Fell und läßt es bei gewöhnlicher Temperatur 3 bis 5 Stunden darin. Ohne Beize erhält man ein leuchtendes Gelb, auch auf Eisenbeize ist die Färbung gelb, ,dagegen auf Chrembedze rötlichbraun und auf Kupferbeize geliblichbraun.Example. The well-cleaned fur is placed in a dyebath containing, per liter, 2 g of 5-nitro-2-amino-i-oxybenzene, 2 g of ammonia, 25 percent, and 30 g of hydrogen peroxide, 3 percent, and it is left at normal temperature for 3 to 5 hours in this. Without a stain, a bright yellow is obtained; the color is yellow on iron stain, while it is reddish-brown on Chrembedze and yellowish-brown on copper stain.
