Abstract

1,272,802. Reactive monoazo dyes. FARBWERKE HOECHST A.G. 12 Aug., 1969 [31 Aug., 1968], No. 40213/69. Heading C4P. The invention comprises water-soluble reactive monoazo dyes of formula wherein R is H or an acyl residue, R<SP>1</SP> is H or a C 1-4 alkyl group, A and A<SP>1</SP> are benzene or naphthalene residues which may be substituted, B is a divalent bridging group, X is a group of formula -(Y) p -SO 2 -CH 2 -CH 2 -Z or -(Y) p -SO 2 -CH = CH 2 bound to A or A<SP>1</SP>, Z is a residue capable of being split off by an alkali and Y is a -CH 2 -, -NH- or -N(alkyl)- group, m and p are 0 or 1 and n is 1 or 2. The dyes are prepared by azo coupling, or when Z is a sulphuric or phosphoric acid ester group, by esterification of the hydroxy-ethylsulphonyl substituted dyes. The dyes give yellow to red shades on cellulose fibres.
