PROBLEM TO BE SOLVED: To obtain the subject dye mixture having remarkably higher color yield than average of color yield of each dye by mixing a specific dye with a specific dye. SOLUTION: This dye mixture comprises (A) one or more dyes of formula I and one or more dyes selected from a group of (B) a dye represented by formula II or (C) a dye represented by formula III [M is H or an alkali metal; D1 and D2 are each benzene or naphthalene; Y is vinyl or ethyl; R1 to R4 are each H, a 1-4C alkyl or alkoxy; R5 is H, Cl, Br or the like; X1 and X2 and X are each F, Br or Cl; Z1 and Z3 are each formula IV (RA and RB are each H, a 1-4C alkyl or the like) or the like; Z0 is formula V (R10 is H or Cl] or one or more dyes selected from a group or dyes represented by formula II and formula III. Furthermore, the dye mixture preferably contains the component A and the component B or C or the components B or C in a mixing ratio of (90:10) to (10:90).
