water soluble disazoverbindungen with arylcarbonamid - diazokomponenten, processes for their manufacture and their use

摘要

New reactive disazo dyes are 1-amino-2,7-bis(N-aryl- or -alkyl-aminocarbonylphenylazo)-8-naphthol-3(4),6-disulfonic acids or alkali metal salts (I), which contain at least one vinylsulfonyl (precursor) group. New reactive disazo dyes are 1-amino-2,7-bis(N-aryl- or -alkyl-aminocarbonylphenylazo)-1-naphthol-3(4),6-disulfonic acids o alkali metal salts of formula (I), which contain at least one vinylsulfonyl (precursor) group (-SO2Z). one of D1, D2 = an N-aryl- or -alkyl-aminocarbonylphenyl group of formula (II); the other D1, D2 = (II) or a phenyl group (III) or a naphthyl group (IV). The full definitions are given in the DEFINITIONS (Full Definitions) Field. An Independent claim is also included for the preparation of dyes (I).
