    • A compound of formula (I) wherein: R and R each independently represents arylamino, diphenylamino, benzylamino or dibenzylamino, and Z represents a leaving group. In general the group -SO2-CH2-CH2-Z is a blocked vinylsulphone and in some cases it is advantageous to use the free vinylsulphone. The leaving group Z may comprise, for example, sulphato (-OSO3 ), S-thiosulphato (-SSO3 ), Sarcosine, N-methyltaurine, N,N-dialkyl acetate (-O-CO-CH3), acyloxy (-O-CO-R, where R is alkyl e,g, C1-C5), phosphato (-OPO 3), or a halogen. Activation of the leaving group is usually by means of heating in slightly acidic baths to produce the fibre reactive vinylsulphone. Alternatively the free reactive vinylsulphone may be pre-formed and applied to the fabric as a dispersion. The compounds of the invention contain more aromatic rings which are not substituted with vinylsulphone groups which has been found to improve pi-bonding. In addition the pi system of the present invention is planar, which has been found to be crucial to increasing the affinity of the fibres to disperse dyes as well as imparting shrink resistance and other properties to the fabric.
    • 式(I)的化合物其中:R 1和R 2各自独立地表示芳基氨基,二苯基氨基,苄基氨基或二苄基氨基,Z表示离去基团。 通常,基团-SO 2 -CH 2 -CH 2 -Z是封端的乙烯基砜,并且在一些情况下使用游离的乙烯基砜是有利的。 离去基团Z可以包括例如硫酸根(-OSO 3 - ),S-硫代硫酸根(-SSO 3 - ),肌氨酸,N-甲基牛磺酸,N,N-二烷基乙酸酯(-O-CO-CH 3) ,酰氧基(-O-CO-R,其中R是烷基e,g,C1-C5),磷酸根(-OPO - 3)或卤素。 离去基团的活化通常是通过在微酸性浴中加热以产生纤维反应性乙烯基砜。 或者,可以预先形成游离的反应性乙烯基砜,并将其施加到织物上作为分散体。 本发明的化合物含有更多未被乙烯基砜基取代的芳族环,已被发现改善了π-键。 此外,本发明的pi系统是平面的,已经发现其对于增加纤维对分散染料的亲和力以及赋予织物的抗收缩性和其它性能是至关重要的。
