Abstract

The invention discloses a blue-to-black disperse dye composition, which comprises a component A, a component B, a component C and a component D. The component A is selected from at least one of the following formula (I), the component B is selected from at least one of the following formula (II), the component C is selected from at least one of the following formula (III), the component D is selected from at least one of the following formulas (IV)-(V), and the component D is selected from at least one of the following formulas (V)-(V). When the dye is applied to dyeing of hydrophobic fiber materials, the dye is excellent in friction resistance, sublimation resistance, washing fastness and color fastness, and is a rare environment-friendly disperse blue black dye variety.

Description

[0001] (1) Technical field [0002] The invention relates to a blue to black dye composition and a dye product, in particular to an environment-friendly blue to black disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] Among the disperse dyes, the blue-black series of dyes are used the most. The traditional dye composition is composed of C.I. Disperse Blue 291:1, C.I. Disperse Violet 93 and C.I. Disperse Orange 76, because C.I. The aromatic amines that are harmful to the human body are produced and are allergic to the human body, and have been listed as banned dyes by Germany and other European Union countries. In recent years, many disperse blue-black dye compositions that replace C.I. Disperse Orange 76 have appeared, such as documents CN1230575A, CN101798472A and CN105111785, etc., but there is still room for further improvement in the color fastness of the dye.
