PURPOSE:To obtain a reactive dye mixture, assuming red color, excellent in brightness, level dyeing properties, detergency, stability with time, various fastnesses to sunlight, etc., and useful for dyeing of cellulosic fiber, etc., by blending specific dyes, etc. CONSTITUTION:The mixture comprises (A) one or more dyes in the form of a free acid expressed by formula I [m is 0 or l; R1 is H, lower alkyl or lower alkoxy; R2 and R3 are H, OH, cyano, alkoxy, carboxy, etc.; A is (substituted) phenylene or (sulfo-substituted)naphthylene; X1 is halogen, etc.; Y1 is SO2CH= CH2 or SO2CH2CH2Z1 (Z1 is a group releasable by the action of alkali)] such as a dye expressed by formula II and (B) one or more dyes in the form of a free acid expressed by formula III [n is 0-2; either of W1 and W2 is H and the other is sulfo group; R7 is H, OH, cyano, etc.; B is (substituted)phenylene or (sulfo-substituted)naphthylene; X2 is N(R8)R9, OR10 (R8 to R10 are H, OH, etc.), etc.; Y2 is SO2CH=CH2, etc.] such as a dye expressed by formula IV. Furthermore, the amount of the component (B) is 0.05-100 times based on the component (A).
