Abstract

The invention relates to a dispersing dye mixture and the dye products that has no thrill to skin and has good application capability. The feature is that the mixture at least contains a kind of dye compounding of formula (I) and a kind of dye compounding of formula (II).

Description

technical field [0001] The invention relates to a dye mixture, in particular to a disperse dye mixture and a dye product thereof. It is mainly used for dyeing and printing hydrophobic synthetic materials or for pre-spun dyeing of hydrophobic synthetic materials. Background technique [0002] The orange azo disperse dye C.I. Diperse Orange 37 has the structure of the following formula: [0003] It is disclosed, for example, in CH-A-0406481, and this dye is often used in the industry in admixture with various other dyes to obtain a range of different shades, especially black. Black disperse dyes in the prior art are all mixed by several disperse dyes. However, the azo disperse dye C.I. Diperse Orange 37 has been found to be skin irritating so that the dyes blended with it are also skin irritating. [0004] The technical problem solved by the present invention is the replacement of orange azo disperse dye C.I.Diperse Orange 37, which is used for blending to obtain a kind o...
