Abstract

The invention discloses a disperse dye composition with high washing fastness. The disperse dye composition is composed of component A represented by structural formula (I), component B represented by structural formula (II), and structural formula (III). Component C shown, component D shown in structural formula (IV), component E shown in structural formula (V), component F shown in structural formula (VI), component G shown in structural formula (VII), Component H shown in the structural formula (Ⅷ) and auxiliary agents are composed; by mass fraction, the mass fraction of the component A is 2 to 10%, and the mass fraction of the component B is 3 to 10%. The mass fraction of component C is 5-10%, the mass fraction of said component D is 8-25%, the mass fraction of said component E is 4-15%, and the mass fraction of said component F is 2 ~10%, the mass fraction of the component G is 3-18%, the mass fraction of the component H is 3-9%, and the rest are auxiliary agents. The invention has excellent washing fastness, rubbing fastness, perspiration fastness, light fastness and coloring rate.
