Abstract:
A method of printing cellulosic fibre material in which the fibre material is brought into contact with a reactive dye of formula: wherein A is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan or dioxazine chromophore, R1, R2 and R3 are each independently of the others hydrogen or unsubstituted or substituted C1-C4alkyl, X1 and X2 are halogen, B is an organic bridging member, T is a reactive radical of formula: R4 is hydrogen, C1-C4alkyl unsubstituted or substituted by hydroxy, sulfo, sulfato, carboxy or by cyano, or a radical â€ƒwherein R5 is as defined hereinbelow, R5 is hydrogen, hydroxy, sulfo, sulfato, carboxy, cyano, halogen, C1-C4alkoxycarbonyl, C1-C4alkanoyloxy, carbamoyl or a group â€”SO2â€”Y, R6 is hydrogen or C1-C4alkyl, alk and alk1 are each independently of the other linear or branched C1-C6alkylene, arylene is an unsubstituted or sulfo-, carboxy-, hydroxy-, C1-C4alkyl-, C1-C4alkoxy- or halo-substituted phenylene or naphthylene radical, Y is vinyl or a radical â€”CH2â€”CH2â€”U and U is a leaving group, Y1 is a group â€”CH(Hal)-CH2(Hal) or â€”C(Hal)&boxH;CH2, wherein Hal is chlorine or bromine, W is a group â€”SO2â€”NR6â€”, â€”CONR6â€” or â€”NR6COâ€”, wherein R6 is as defined hereinabove, Q is a radical â€”Oâ€” or â€”NR6â€”, wherein R6 is as defined hereinabove, n is the number 0 or 1, and V1 and V2 are each independently of the other N, Câ€”H, Câ€”Cl or Câ€”F, wherein the fibre material is dried at temperatures of from 125 to 150Â° C., and the fixing of the printed fibre material is carried out without an additional fixing process step.
