Abstract

1295110 Anthraquinone dyestuffs BAYER AG 19 Oct 1970 [18 Oct 1969] 49553/70 Heading C4P The invention comprises anthraquinone dyestuffs of the general formula wherein R 1 is an optionally substituted aromatic, aliphatic, araliphatic or cycloaliphatic radical. R 1 is preferably phenyl. They are prepared by reacting 1 - sec. - butyl - amino - 4 - bromoanthraquinone - 5 - sulphonic acid with an amine R 1 NH 2 in aqueous medium in presence of an acid binding agent and optionally copper or a copper salt as catalyst. The products may be subsequently brominated or sulphonated in radical R 1 and if R 1 contains a further amino group this may be acylated. Aliphatically linked OH groups may be sulphated and any acylamino groups present in the dyestuffs hydrolysed. The dyes give green-blue shades on wool, silk and synthetic polyamides.
