REACTIVE DYE MIXTURE AND ITS APPLICATION

PROBLEM TO BE SOLVED: To obtain a reactive dye mixture which, when used in dyeing or printing a cellulosic fibrous material, exhibits excellent dye exhaustion characteristics, solubility, level dyeing properties, and stability in an alkyli bath and has various good fastnesses by mixing specified reactive dyes with each other. SOLUTION: This mixture contains at least two reactive dyes represented by formula [wherein R1 is a halogen, a 1-4C alkyl, ureido, a (substituted) 1-4C alkylcarbonylamino or the like; R2 is hydrogen; R3 is hydrogen, a 1-4C alkyl, a 1-4C alkoxyl or the like; R4 and R5, which are independent of each other, are each hydrogen or a (substituted) 1-4C alkyl; B1 and B2, which are independent of each other, are each a (substituted) phenylene or naphthylene group; Y1 and Y2, which are independent of each other, are each -CH2CH2L (wherein L is a group which can leave upon the action of an alkali), vinyl, or -CH2CH2 OH (provided that not both of Y1 and Y2 can be simultaneously -CH2CH2OH groups); (m) is 1 or 2; and (n) is 0 or 1, provided that m+n -2 or 3].
