Abstract

1342858 Disazo dyes BAYER AG 14 Aug 1972 [14 Aug 1971] 37830/72 Heading C4P The invention comprises disazo dyes of formula where K is a hydroxyaminohydroxy or aminonaphthalene coupling component radical which may be further substituted and R is a C 1 -C 6 alkyl radical. The dyes may be obtained by coupling a tetrazotized 4,41-diamino-3,3<SP>1</SP>-dialkoxydiphenyl with 1-amino-8-hydroxy-naphthalene - 3,6 - disulphonic acid in an acid medium and coupling the resulting monoazo compound with a coupling component KH in an acid or alkaline medium. The dyes give blue shades on fibres containing hydroxyl groups or nitrogen, e.g. cotton and regenerated cellulose, and on leather, paper pulp and formed paper.
