PROBLEM TO BE SOLVED: To solve the problem wherein a disperse dye mixture, which can give dyeing which shows improved fastness and improved buildup behaviors, is necessary when a particularly clear hue is made in a polyester fiber of an ultrafine denier of 0.1 to 0.7 denier and in a polyester fiber of a regular denier of e.g. 1 to 5 denier. SOLUTION: A clear hue can be obtained only when a mixture of different dyes clearly distinct according to a subtractive color mixture theory is used. In this case, three dye hues having ideal colors, i.e. cyan, yellow, and magenta (three color dyeing) are necessary. A dye mixture of non-azo disperse dyes has been found out. These satisfy use requirements in three-color dyeing and which, when used in exhaustion dyeing, can give very uniform dyeing having a very good light fastness to an ultrafine denier polyester fiber of, e.g. 0.1 to 0.7 denier, a regular-denier polyester fiber of e.g. 1 to 5 denier, or a synthetic fiber material, and a mixed fiber thereof.
