    • Reactive Dye compound having formula (I) wherein: D is a chromophore group; L is a linking moiety; Q is a quaternized nitrogen derivative; X and Y are independently selected from chlorine, bromine, fluorine or hydrogen; A is selected from halogen, preferably chlorine or fluorine; provided that at least one of X and Y is fluorine; A is selected from halogen, preferably chlorine or fluorine; and salts and esters thereof. The reactive dye compounds of the invention have high Exhaustion Values, high Fixation Values, particularly on cellulosic substrates such as cotton, and show significant improvements in terms of reducing spend 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 therefor simplying the post dyeing “soaping off process” traditionally associated with dyeing cotton with fiber 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.
    • 具有式(I)的活性染料化合物,其中:D是发色团; L是连接部分; Q是季铵化的氮衍生物; X和Y独立地选自氯,溴,氟或氢; A选自卤素,优选氯或氟; X和Y中的至少一个为氟; A选自卤素,优选氯或氟; 及其盐和酯。 本发明的活性染料化合物具有高的耗尽值,高固定值,特别是在诸如棉花等纤维素基质上,并且在减少流出物中的花费染料方面显示出显着的改进,增加染料底物共价的染料亲和性 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,因此简单地将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。
