Abstract (en)
[origin: WO9839308A1] A compound of formula (I) wherein: R<1> and R<2> 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 <u>not</u> 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.
