    • 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. In addition, the compounds prepared above provide more intense dyeings and require less levels of salt for dyeing cotton substrates.
    • 一种活性染料化合物,其包含(a)至少一个生色团部分; (b)至少一个SO2C2H4基团,其通过SO 2 C 2 H 4基团的硫原子或连接基团L直接附着于发色团部分; 其特征在于至少一个SO 2 C 2 H 4基团在其末端碳原子上被至少一个Y基团取代,其中Y衍生自水合醛,水合酮,水合α-羟基酮或甲酸的水合形式,并连接 通过其氧原子之一与SO 2 C 2 H 4基团的末端碳键合形成半缩醛。 本文的化合物具有高的耗尽值(E),高固定值(F)和高效率值(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 粘合,增加了在室温下染色基质的能力,减少了在后染色“皂洗过程”期间除去的染料的量,从而简化了传统上与纤维活性染料染色棉相关的后染色“皂洗过程” 减少相邻白色织物的染色。 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。
