| abstract | 1316724 Disazo dyes BAYER AG 19 April 1971 [14 Feb 1970 10 Oct 1970] 21629/71 Heading C4P The invention comprises disazo dyes of formula wherein W is a radical of formula In the above formulae R 1 is H or an optionally substituted alkyl or phenyl group; R 2 and R 3 independently represent H, halogen, an optionally substituted alkyl or alkoxy group or an acylamino group; R 4 is H, halogen or optionally substituted alkyl, alkoxy or an acylamine group; R 5 is H or an optionally substituted alkyl or alkoxy group; R 6 and R 7 independently represent hydrogen, hydroxy, cyano, halogen, acyloxy, alkoxycarbonyl, or an optionally substituted phenyl group; X is a C 1 -C 4 alkylene radical; R 8 is an unsubstituted alkyl, phenyl or 2-naphthyl or 4-biphenylyl group; R 9 is H, C 1 -C 6 alkyl group optionally substituted by a nitrile, carbamoyl or carboxyl group; R 10 is a substituent and n is 0, 1 or 2. The dyes are obtained by diazotizing a monoazo dyestuff of formula and coupling it with the required amine or indole. The monoazo dyes of Formula IV are obtained by coupling a diazotized aniline sulphonic acid with a coupling component of formula where Z represents a radical which may be split off by hydrolysis, e.g. sulphoalkylene a sulphonic acid. The group -NHZ is converted to an NH 2 prior to diazotization of the aminomonoazo compound. The dyes give red shades on synthetic fibre materials especially polyamides, e.g. poly #-caprolactam and condensate products of adipic acid and hexamethylene diamine. |
