Abstract

1330277 Metallized disazo dyes BAYER AG 30 March 1972 [1 April 1971] 15027/72 Heading C4P New metallized disazo dyes of formula wherein A is an aromatic-carbocyclic radical, M is an optionally substituted 1,4-phenylene or -naphthylene group with a-(CO) n O-group in o-position to the azo bridge M-N=N-E, E is the radical of a coupling component, X is -O- or -NH-in a position adjacent to the azo bridge, n is 0 or 1 and A, M and E together possess one SO 3 H group are prepared by coppering the disazo dyes, which are themselves prepared by successive azo coupling reactions. The dyes are used to colour polyamide fibres in blue shades.
