Abstract

1404090 Disazo dyestuffs derived from 4,4<SP>1</SP> - diaminodiphenylamine - 2 - sulphonic acid BAYER AG 20 Dec 1973 [21 Dec 1972] 59105/73 Heading C4P Novel dyestuffs of the formula (wherein K is the radical of an azo-group-free coupling component) are prepared by coupling tetrazotized 4,41-diaminodiphenylamine-2-sulphonic acid with 2-amino-8-hydroxy-naphthalene-6-sulphonic acid in acid medium in the molar ratio of 1 : 1 and subsequently coupling with KH. They are suitable for dyeing natural and synthetic textile materials, e.g. wool and polyamides, cotton and rayon.
