A method of printing cellulosic fiber materials in which the fiber material is brought into contact with reactive dyes of formula:whereinA 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 radicalwherein R5 is as defined hereinbelow,R5 is hydrogen, hydroxy, sulfo, sulfato, carboxy, cyano, halogen, C1-C4alkoxycarbonyl,C1-C4alkanoyloxy, carbamoyl or a group -SO2-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 -CH2-CH2-U and U is a leaving group,Y1 is a group -CH(Hal)-CH2(Hal) or -C(Hal)=CH2, wherein Hal is chlorine or bromine,W is a group -SO2-NR6-, -CONR6- or -NR6CO-, wherein R6 is as defined hereinabove,Q is a radical -O- or -NR6-, wherein R6 is as defined hereinabove,n is the number 0 or 1, andV1 and V2 are each independently of the other N, C-H, C-Cl or C-F,and the fixing of the printed fiber material is carried out without an additional fixing process step.The prints obtained are distinguished by brilliant colour shades and good allround properties.
