Abstract

1,190,543. Water-soluble anthraquinone dyestuffs. FARBENFABRIKEN BAYER A.G. 22 Jan., 1969 [26 Jan., 1968], No. 3588/69. Heading C4P. The invention comprises water-soluble anthraquinone dyestuffs of the general formula wherein R is C 1 -C 6 alkyl and n is 5 to 11. They are prepared by (a) condensing a 1-amino-2- sulphonic acid - 4 - (p alkoxy) phenylaminoanthraquinone with an appropriate N-methyl cyclic amide, the N-methyl group being substituted by a radical X which can be split off as HX in presence of an acidic condensing agent, e.g. X may be OH, alkoxy, Cl or Br and preferred condensing agents are 80-100% sulphuric acid, 80-100% phosphoric acid or a glacial acetic acid/HCl mixture or (b) by reacting 1 - amino - 4 - bromo - anthraquinone - 2 - sulphonic acid with a compound of the formula wherein R and n are as above. The dyes give greenish-blue shades on leather, wool, silk and synthetic polyamides.
