Blue-to-black disperse dye composition and dye product

Abstract

The invention discloses a blue-to-black disperse dye composition which comprises a component A, a component B and a component C. The component A is selected from at least one of compounds shown in a formula (I), the component B is selected from at least one of compounds shown in a formula (II), and the component C is selected from at least one of compounds shown in a formula (III). When the blue-to-black disperse dye composition provided by the invention is applied to dyeing of hydrophobic fiber materials such as polyester and blended fabrics thereof, various fastness properties, especially sublimation fastness resistance, are excellent;.

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 dyes are used in the largest amount. 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, there have been many disperse blue-black dye compositions replacing C.I. Disperse Orange 76, such as documents CN1230575A, CN101798472A and CN105111785. [0005] However, it has recently been discovered that C.I. Disperse Violet 93 is also ecologic...

AI Technical Summary

Problems solved by technology

[0005] However, it has recently been discovered that C.I. Disperse Violet 93 is also ecologically unsafe. It is imminent to find a new type of disperse blue-black series dye that is environmentally friendly and has excellent color fastness.
