Abstract

Brown vat dyes are obtained by first condensing a derivative of 1 : 2-naphthoquinone containing a mobile substituent with an o-diamino-anthraquinone and then condensing the product with a mono- or dia -aminoanthraquinone. According to examples, the following components are employed:-3- or 6-brom-1 : 2-naphthoquinone, 2 : 3- or 1 : 2-diaminoanthraquinone, and 1-amino- or 1 : 5-diamino-anthraquinone.
