Embodiment 1

[0034] Component A shown in 20.0 grams of formula (1-1), component B shown in 16.5 grams of formula (2-1), component C shown in 8.5 grams of formula (3-1) are mixed, with pulverizer Pulverize and mix to obtain the disperse black dye composition of the present invention.

[0035] 45 grams of the above-mentioned disperse black dye composition, 55 grams of dispersant MF and 200 grams of water are ground together with a sand mill (micronized and dispersed), and then spray-dried to obtain a solid product of the disperse black dye composition. Based on the dye compound components used, wherein the mass fraction of component A shown in formula (1-1) is 44.4%, the mass fraction of component B shown in formula (2-1) is 36.7%, and the mass fraction of component B shown in formula (3-1) is The mass fraction of component C is 18.9%.

[0036] The dispersion stability of the disperse dye of the present invention at 71°C and 130°C was tested respectively according to GB / T 5540 and GB / T 5541...

Embodiment 2～3

[0039] With reference to the method of Example 1, and the consumption of each component shown in Table 1, a solid product of the disperse black dye composition of the corresponding embodiment was prepared.

Embodiment 4

[0041] With reference to the method of Example 1, and the consumption of each component shown in Table 1, grind and disperse with a sand mill, filter out the dye slurry with a filter screen when the particle diameter is less than 2 microns, and obtain the corresponding disperse black dye composition liquid products.

Abstract

The invention discloses a disperse black dye composition, a dye product and an application. The disperse black dye composition is characterized by comprising a component A shown in a formula (1), at least one component B shown in formulas (2-1) and (2-2) and at least one component C shown in formulas (3-1) and (3-2). The invention also discloses the dye product containing the composition, the application and a coloring product containing the composition. The disperse black dye composition is high in performance of all items, staple products such as disperse black ECT and the like related in the patent ZL99104177.1 can be directly replaced, light jumping (metamerism indexes meet a general requirement) is avoided, and the components are not involved with reduced products.

Description

[0001] Technical field: [0002] The invention relates to a disperse black dye composition, a dye product and its application, in particular to a disperse dye composition containing a specific structure suitable for printing and dyeing hydrophobic fiber materials, especially suitable for dyeing polyester fiber materials. [0003] Background technique: [0004] Securities Daily reported on a patent infringement case with patent number ZL99104177.1 on November 30, 2012. The plaintiff required the infringing company to immediately stop producing, selling and promising to sell dye products protected by the Chinese patent ZL99104177.1, and to compensate the plaintiff’s economy. A loss of 100 million yuan. According to the data, the patent-infringing products involved in the case are black mainstream varieties of disperse dyes, and black is the largest variety of dyes in all shades. The patent-infringing products involved in the case account for about 50% of the total output value of...
