Abstract

1,211,804. Water-soluble monoazo dyes. FARBWERKE HOECHST A.G. 27 May, 1968 [27 May, 1967], No. 25144/68. Heading CAP: Water-soluble monoazo dyes of general Formula I in which A 1 and A 2 , are each an aryl radical of the benzene or naphthalene series, D is an alkyl radical containing 1-4 carbon atoms a carboxylic or carboxylic acid alkyl ester group, m is 0-3 and n is 0-1 the sum of m and n being at least 1, X is -NHCO- or -NHSO 2 - and Z is. one of the groupings -SO 2 CH 2 CH 2 Y, -SO 2 CH=CH 2 , -SO 2 CH 2 CH 2 OH, in which Y is a radical which can be split off by alkaline agents, R 1 is hydrogen or chlorine or an alkyl group, and R 2 is hydrogen or chlorine or an alkoxy group, are prepared by diazotizing an amine of formula and coupling with a pyrazolene of Formula II in which A 1 , A 2 , X 1 , m and n, D, R 1 , R 2 and Z are as above, provided a hydroxy ethyl sulphonyl radical is present the hydroxy group being esterified by known methods with concentrated sulphuric acid or an agent yielding sulphur trioxide. The dyes give yellow shades on wool, silk, cellulose and polyamides.
