Zusammenfassung:PURPOSE:To obtain the title composition improved in build-up, solubility, long- term stability, fastness, etc., by mixing two specified reactive dyes. CONSTITUTION:In an aqueous medium, 2-aminonaphthalene-8,6,8-trisulfonic acid is diazotized, coupled with 1,3-diaminobenzene, converted into a ureide by using a cyanate to give a reactive dye (A) of formula I (wherein Z' is -CH=CH2 or -CH2CH2Z2; Z2 is a group eliminable by an alkali) in free acid form. A reactive dye (B) of formula II (wherein Z is -CH=CH2 or -CH2CH2Z1; Z1 is a group eliminable by an alkali) in free acid form is mixed with component A in an amount of 1-30wt.% based on component B to give the title composition. A fibrous material containing OH groups or carboxamido groups is dyed or printed with this composition.
