PROBLEM TO BE SOLVED: To obtain a dyed article having a high fixing ratio and a good wet fastness by incorporating a dye comprising a chromophore radical and 2,4- difluoropyrimidin-6-yl and a dye comprising a chromophore radical and 4,6- difluoropyrimidin-2-yl into the same. SOLUTION: This dye mixture comprises 85-50 wt.% at least one dye represented by the formula: A.XA and 15-50 wt.% at least one dye represented by the formula: A.XB and is very useful for dyeing or printing a natural or synthetic OH-contg. material (e.g. cellulose) and/or amide-contg. material (e.g. a polyamide). In the formulas, XA is 2,4-difluoropyrimidin-6-yl; XB is 4,6- difluoropyrimidin-2-yl; and A is a chromophore radical represented by formula I, II, or III or the like (wherein R is H, 1-6C alkyl, or the like; R1 is H, CH3, or the like; R2 is a group such as 1-4C alkyl optionally substd. by NH2, OH, or the like; R3 is a group such as phenyl optionally substd. by halogen or SO3H; and D is benzene, naphthalene, or the like).
