The preparation of new monoazo dyes from substituted 5‐nitw‐2‐aminobenzothiazole‐3N‐oxides and aniline coupling components and their dyeing properties on polyester, cellulose acetate, nylon 6 and acrylic fibres are reported. The dyes exhaust well on synthetic‐polymer fibres to give bright dyeings of good fastness to dry cleaning and sublimation. Their light fastness is better than that of dyeings of the unnitrated dyes. However the transferability of the nitro dyes is such that they are unsuitable for sublimation printing. The transferability of other dyes derived from 2‐aminobenzothiazole‐3N‐oxide and its derivatives is also assessed.
