Abstract

1,271,301. Mono- and dis-azo dyes. FARBENFABRIKEN BAYER A.G. 9 April, 1969 [16 April, 1968], No. 18223/69. Heading C4P. New mono- and dis-azo dyes of formula wherein one X is SO 3 H and the other is H or SO 3 H, R is H or alkyl which may be substituted, Q is an -R 1 -SO 2 -R 2 group, wherein R 1 is an arylene radical which may be substituted, R 2 is an optionally substituted alkyl, aryl cycloalkyl, aralkyl or heterocyclyl radical and n is 1; or R 2 has a meaning as stated for R 1 and n is 2; or the radicals R 1 and R 2 form a ring with the -SO 2 - group and n is 1 or 2, are prepared by azo coupling of diazotized amines Q-NH 2 or H 2 N-Q-NH 2 with 2-amino-8-naphthol-sulphonic acids. The dyes may be used to colour polyamide fibres, or if they contain fibrereactive groups, also cellulose fibres, in red shades.
