    • 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 simplifying 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.
    • 通过固定值技术测试方法(以2:1标准深度)测量,在纤维素基材上具有95%或更高固定值(F)的活性染料。 此外,本文的化合物具有高的耗尽值(E),高效率值(T),并且在减少流出物中的废染料方面显示出显着的改善,增加了对基材的染料亲和力,增加了染料 - 底物共价键,增加了 在室温下染色基质的能力,减少在后染色“皂洗过程”中除去的染料的量,因此简化了与纤维活性染料染色棉相关的后染色“皂洗过程”,并减少染色 相邻的白色面料。 此外,上述制备的化合物提供更强烈的染色,并且需要较少量的盐用于染色棉花基质。

    • A reactive dye compound comprising (a) at least one chromophore moiety; (b) at least one SO2C2H4 group which is attached to the chromophore moiety either directly via the sulphur atom of the SO2C2H4 group or via a linking group L; characterised in that at least one SO2C2H4 group is substituted on its terminal carbon atom with at least one Y group wherein Y is derived from a hydrated aldehyde, a hydrated ketone, a hydrated alpha-hydroxy ketone or the hydrated form of formic acid, and linked via one of its oxygen atoms to the terminal carbon of the SO2C2H4 group thereby forming a hemiacetal. The compounds herein have high Exhaustion Values (E), high Fixation Values (F) and 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 simplifying the post dyeing "soaping off process" traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics.
