Embodiment 1

[0056] With 55 grams of formula (I-1) compound, 20 grams of formula (II-1) compound, 25 grams of formula (III-1) compound and 250 grams of dispersant MF, after adding 650 grams of water, blending, grinding and dispersing and drying, The finished product is obtained. The dye can provide yellow color with excellent fastness properties to the fabric.

Abstract

The invention discloses a disperse yellow dye composition, its product and an application thereof. The disperse yellow dye composition comprises a component A, a component B and a component C. The component A is at least one selected from compounds represented by a following formula (I), and the component B is at least one selected from the compounds represented by a following formula (II), and the component C is at least one selected from the compounds represented by a following formula (III), based on the component A, the component B and the component C, the mass percentage of the componentA is 10 to 90%, the mass percentage of the component B is 5 to 85%, and the mass percentage of the component C is 5 to 60%. A disperse yellow dye preparation contains the disperse yellow dye composition and an adjuvant. The disperse yellow dye composition and the product can be used in the printing and dyeing of a hydrophobic fiber material, have good compatibility, good level-dyeing property, good pH dependence, excellent light fastness resistance, sublimation resistance, and washing fastness resistance.

Description

(1) Technical field [0001] The invention relates to a disperse yellow dye composition and its products, as well as its application in printing and dyeing of hydrophobic fiber materials. (2) Background technology [0002] There are many types of yellow disperse dyes, such as disazo-type disperse yellow 23, which is banned because it is easy to decompose the carcinogenic aromatic amine 4-aminoazobenzene; Good, it is suitable for many kinds of fibers, and the dyeing performance needs to be improved; the quinoline-based Disperse Yellow 54 has bright shades. In recent years, with the prohibition of Disperse Yellow 23, its usage is increasing. The above three disperse dyes can be colored under weak alkaline conditions, but are sensitive to strong alkali. [0003] Polyester fabrics must undergo alkali reduction (alkali boiling) before dyeing, and then wash with a large amount of water to remove residual alkali. Due to incomplete washing, residual alkali is brought into the dye bat...
