The fiber-reactive disazo dyes (I) [R=vinyl, CH2CH2OH or CH2CH2R1; R1=alkali-removable gp.; R2=(un)substd. alkoxy, alkyl, halogen, CF3; R3=H, (un)substd. alkoxy, halogen, alkyl; R4=H, (un) substd. alkyl, alkenyl, Z2SO3M; Z=(un)substd. phenylene, naphthylene, 2- benzothiazoyl gp. with RSO2(CH2)n on benzo ring; Z1=(un) substd. 1,4- phenylene, naphthylene; Z2=(CH2)2, (un)substd. C3H6, CH2CH2O, CH2CH2C6H4, CH2C6H4; M=H, metal; n=0-2 are prepd. Thus, 3,4- HO3S(H2N)C6H3SO2(CH2)2OSO3H is diazotized, coupled with m-MeC6H4NH2, the aminoazo compd. diazotized, coupled with m-ClC6H4NCH2CH2OSO3Na)2, and salted to give II.
