Embodiment 1

[0022] With 12 gram formula (I-1) compound, 12 gram formula (I-2) compound, 40 gram formula (II-2) compound, 18 gram formula (III) compound, 18 gram formula (IV-1) compound and 200 After adding 650 grams of water and blending the dispersant MF of 100 grams, it is ground and dispersed and dried to obtain the finished product. This dyestuff can provide the excellent black color of the various fastness properties of the fabric.

[0023]

Embodiment 2

[0025] With 30 gram formula (I-1) compound, 30 gram formula (I-2) compound, 20 gram formula (II-1) compound, 10 gram formula (III) compound, 10 gram formula (IV-1) compound and and 200 grams of dispersant MF, after adding 650 grams of water and blending, grinding, dispersing and drying, the finished product is obtained. The dye can provide blue color with excellent fastness properties to fabrics.

[0026]

Embodiment 3～30

[0028] According to the method described in embodiment 1 or 2, the difference is to adopt the structure and weight of components A~D in table 1, add 250 grams of auxiliary agents (dispersant MF is 200 grams, sodium lignosulfonate is 50 grams) , add 800 grams of water and blend to make a slurry, grind and disperse, and dry to obtain a finished product. The dye can provide blue to black fabrics with excellent fastness properties.

Abstract

The invention discloses a high-fastness blue-black disperse dye composition and a dye product. The blue-black disperse dye composition comprises a component A, a component B, a component C and a component D, wherein the component A is a compound shown in Formula (I-1) and / or (I-2); the component B is a compound shown in Formula (II-1) and / or (II-2); the component C is a compound shown in Formula (III); and the component D is a compound shown in Formula (IV-1) and / or (IV-2) and / or (IV-3).The blue-black disperse dye product contains the blue-black disperse dye composition and aids. When the blue-black disperse dye composition and dye product provided by the invention are applied to dyeing of a hydrophobic fiber material, the lifting power is high, the deep dyeing property is favorable, the dispersity is favorable, the level dyeing property is fine, and the color fastness indices are excellent. The formulas are all shown in the specification.

Description

[0001] (1) Technical field [0002] The invention relates to a blue to black disperse dye composition and a dye product, in particular to a high fastness 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, but at present, it is difficult for this series of dyes to have excellent dyeing performance and fastness performance. Blue-black series dye composition, but there is still room for further improvement in terms of lifting power and dispersibility. [0005] (3) Contents of the invention [0006] In order to solve the above problems, the present invention provides a high-fastness blue to black disperse dye composition and dye products. When applied to the dyeing of hydrophobic fiber materials, it has high lifting power, good dyeing depth, good dispersibility and level dyeing property. ...
