The present invention relates to a disperse dye composition comprising 1-99 parts by weight of a compound of chemical formula 1 below and 1-99 parts by weight of a compound of chemical formula 2 below, and to a method for dyeing semi-synthetic fibers, synthetic fibers, regenerated fibers, or mixed fibers of synthetic fibers and natural fibers, by using the disperse dye composition. The disperse dye composition according to the present invention comprises a combination of specific compounds, and thus the disperse dye composition shows an excellent dye adsorption rate when dyeing a mixed fiber material including polyester or the like, has excellent allround fastness, such as sunlight fastness, water fastness, and sublimation fastness, and enables the expression of high-density colors. [Chemical formula 1] [Chemical formula 2] In chemical formula 2, R1 is a hydrogen atom or (C1-C18)alkyl; R2 is (C1-C18)alkyl or -(CH2)n-CO2Ra; n is an integer of 1 to 8; and Ra is (C1-C18)alkyl or (C1-C8)alkoxy ...
