PURPOSE: Provided is a mixtures of disperse azo dyes which does not cause irritation to the skin and lends to the mixture excellent heat fastness. CONSTITUTION: The dye mixture comprises at least (1) (A) at least one azo dye of the formula(1), wherein each of X and X independently is chlorine or bromine; R is absent or is C1-4 alkyl; and each of R and R independently is hydrogen, C1-6 alkyl or cyanoethyl; but when R is absent, R is n-butyl or cyanoethyl and R is cyanoethyl; and (B) at least one azo dye of the formula(2), wherein X is absent or is chlorine or bromine; each of R and R independently is hydrogen, C1-4 alkyl, allyl or acyloxyalkyl; R is C1-4 alkyl or NHCOY, in which Y is hydrogen, C1-4 alkyl, or NH2; and R is C1-4 alkoxy; and at least when, in the formula(1), R is absent and, in the formula(2), X is bromine, R is NHCOY(in which Y is methyl), R is methoxy and each of R and R is allyl or one of R and R is allyl and the other is hydrogen (C) at least one azo dye of the formula(3), wherein X is absent or is chlorine or bromine; R is C1-4 alkyl or NHCOY, in which Y is hydrogen, C1-4 alkyl or NH2; and each of R and R independently is hydrogen, C1-4 alkyl, allyl or acyloxyalkyl; or (2) (A) at least one azo dye of the formula(1), given and defined above, wherein R is absent, R is n-butyl or cyanoethyl and R is cyanoethyl; and (D) at least one azo dye of the formula(4), wherein R is absent or is C1-4 alkyl; R is hydrogen, cyano, hydroxyl, OCOR or OCOOR in which R is C1-4 alkyl, aryl or aralkyl; R is hydroxyl, OCOR in which R is as defined above; and each of m and n independently is 1, 2, 3 or 4.
