Abstract
1333522 Disazo dyes BAYER AG 3 March 1972 [4 March 1971] 10060/72 Heading C4P New disazo dyes of formula wherein A is a C 2-5 alkylene radical, B is a 1,4-phenylene or -naphthylene radical, R 1 , R 2 and R 3 are H, Cl, Br, alkyl or alkoxy, R 4 is an unsubstituted alkyl or optionally substituted phenyl group, R 5 is H or an alkyl group optionally substituted by CN, CONH 2 or COOH, R 6 is a substituent, m is 1,2, 3 or 4 and n is 0,1 or 2 are prepared by coupling a diazotized p-sulphato- or hydroxy-alkoxy-aniline with an aniline or 1-naphthylamine which may be N-substituted by -SO 3 H or -CH 2 SO 3 H, removing this group by hydrolysis if necessary, further diazotizing and coupling with a 2-substitutedindole and finally sulphating the hydroxy group if necessary. The dyes are used to colour natural and synthetic polyamide fibres in red shades.
