A process for the preparation of a dye mixture, which comprises the step of diazotising a compound of formula D-NH2 and coupling the diazonium compound so obtained to a coupling component mixture comprising the coupling components of formulae wherein D is the radical of a diazo component of the benzene, naphthalene, diphenyl, azobenzene, thiophene, benzothiazole, benzisothiazole, thiazole, thiadiazole, indazole, benzotriazole, pyrazole, anthraquinone. hydroxynaphthoic acid imide, chromone or diphenylene oxide series, X is in each case hydrogen, halogen, CF3, R3, OR3, NH-CO-R7, NH-CQ-OR8, NH-SO2-R7 or NHCO-NR4A5, wherein R3 is C1-C6alkyl, R4 and R5 are each independently of the other hydrogen, C1-C4alkyl or C1-C4alkoxy-C2-C4-alkyl, R7 is hydrogen, C1-C6alkyl, C1- C4alkoxy-C1,-C4alkyl or phenyl, and R8 is C1-C6alkyl or C1-C4alkoxy-C2-C4alkyl, and Y is in each case hydrogen, halogen, methoxy, ethoxy or O(CH2)n-OR9, wherein R9 is hydrogen, methyl CH2CH2CN, and n is an integer from 1 to 6. 0 CIBA SPECIALTY CHEMICALS HOLDING INC, 331/MAS/1998A 331/MAS/1998 INDIA 2009-03-27T15:56:23Z 2006-10-27 1998-02-19 424178 C09B 67/22 17975 0 160 2006-10-27 0 4FAIuLDg 2009-04-30T22:21:05Z 2334 CIBA SPECIALTY CHEMICALS HOLDING 53569 /app_images/d/9/8/5/46R1067.jpg
