PROBLEM TO BE SOLVED: To obtain a printing mixture which can dye or print an OH- or Ncontg. fiber material by compounding at least one dye represented by formula I with at least one dye represented by formulae II and III. SOLUTION: This dye mixture comprises at least one dye represented by formula I and at least one dye represented by formula II or III. In the formulae, R1 to R4 and R6 represent each H or a 1-4C (substd.) alkyl; R5 represents H, a C1-6 (substd.) alkyl, a C5-7 cycloalkyl, phenyl (substd. by a C1-4 alkyl, an alkoxy or the like), naphthyl (substd. by a C1-4 alkyl, an alkoxy or the like); R7 represents a 1-6C (substd.) alkyl, a 2-4C alkenyl, phenyl, or naphthyl; X1 and X2 represents each a halogen, OH, a C1-4 alkoxy, amino or the like; and A1 to A4 represent each a dye group, such as monoazo or diazo. This dye mixture is suitable for dyeing or printing N- or OH-contg. fiber materials, papers, leathers, particularly woven fabric materials of wool and synthetic polymides. The print has good fastness and in addition is easily soluble in water and can be easily used in combination with other dye(s).
