| Abstract: | The preparation of reactive azo cationic dyes containing a vinylsulphonyl group derived from 2-aminobenzothiazole and its derivatives is described. Their dyeing properties on blends of acrylic–cellulosic, polyester–cellulosic fibre and on cotton and synthetic fibres are investigated. The relationship between absorption spectra and pH of dye solution is assessed. |
