Abstract

The invention discloses a yellow disperse dye composition which comprises a component A and a component B, wherein the component A is selected from compounds shown in a formula (Ia) and / or a formula (Ib), and the component B is selected from at least one of compounds shown in a formula (II). The invention further provides a yellow disperse dye product which contains the yellow disperse dye composition and an auxiliary agent. The invention also provides the application of the yellow disperse dye product in dyeing of hydrophobic fiber materials, and the yellow disperse dye product has the characteristics of good high-temperature dispersibility, excellent color fastness to water washing and the like.

Description

[0001] (1) Technical field [0002] The invention relates to a yellow dye composition and a dye product, in particular to a yellow disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] With the continuous improvement of living standards, people have higher and higher requirements for the quality of textiles. Correspondingly, higher requirements have been put forward for the color fastness of dyed dyes. There are various yellow dispersions with excellent color fastness on the market. There are not many kinds of dyes. C.I. Disperse Yellow 23 is widely used due to its excellent color fastness, but it is listed as a banned dye by the European Union due to the production of aromatic amine carcinogens under certain conditions. There is an urgent need to find a substitute for C.I. Disperse Yellow 23. [0005] (3) Contents of the invention [0006] The invention provides a yellow disperse d...
