Description
Zusatzpatent zum Hauptpatent Nr.131100. Verfahren zur Herstellung eines neuen, als Farbstoff verwendbaren Produktes. Es wurde gefunden, dass man ein neues Produkt erhält, wenn man Benzaldehyd, Bisulfit und 1,4-Oxyaminoanthrachinon auf einander einwirken lässt.
Das neue. Produkt bildet in trockenem Zustande ein rotviolettes Pulver, das in Wasser leicht löslich ist und Acetatseide in klaren violettroten Tönen färbt. <I>Beispiel</I> 5 Teile 1,4-Ogyaminoanthrachinon werden, am besten in Form einer konzentrierten Paste, mit 15 Teilen Benzaldehyd, 70 Teilen Bisulfit und 50 Teilen Wasser unter Rühren auf 95 erwärmt, bis eine Probe in Wasser klar löslich ist. Man dampft zur Trockne ein.
Additional patent to main patent number 131100. Process for the preparation of a new product which can be used as a dye. It has been found that a new product is obtained if benzaldehyde, bisulfite and 1,4-oxyaminoanthraquinone are allowed to act on one another.
The new. When dry, the product forms a red-violet powder that is easily soluble in water and dyes acetate silk in clear violet-red tones. <I> Example </I> 5 parts of 1,4-ogyaminoanthraquinone, ideally in the form of a concentrated paste, are heated to 95 with 15 parts of benzaldehyde, 70 parts of bisulfite and 50 parts of water while stirring until a sample is clearly soluble in water is. It is evaporated to dryness.
