Abstract (en)

[origin: WO9951686A1] Reactive dye having a Fixation Value (F) on cellulosic substrates of 95 % or greater as measured by the Fixation Value Technical Test Method (at 2:1 standard depth). In addition, the compounds herein have high Exhaustion Values (E), high Efficiency Values (T) and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, increasing the dye-substrate covalent bonding, increasing the ability to dye substrates at room temperature, decreasing the amount of dye that is removed during the post dyeing "soaping off process" and therefore simplying the post dyeing "soaping off process" traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics. In addition, the compounds prepared above provide more intense dyeings and require less levels of salt for dyeing cotton substrates.
