PURPOSE:The titled dye mixture for dyeing synthetic fibers such as polyester fibers, etc., or clothes made therefrom in orange in improved fastness to light, sublimation and wetting fastness after post-treatment, obtained by blending two kinds of disazo dye shown by specific structural formulas in a specific ratio. CONSTITUTION:(A) Disazo dye shown by formula I is blended with (B) disazo dye shown by formula II (R is methyl or 3-8C alkyl) in a weight ratio of 20:80-80:20, preferably 30:70-70:30 to give the aimed dye mixture. The dye, for example, can be obtained by diazotizing an amine shown by formula III and then coupling it with a compound shown by formula IV and a compound shown by formula V, respectively, to give dye shown by formulas I and II.
