Abstract

The invention discloses a dispersed black azo dye mixture. The product at least contains a compound of the following formula (I) and at least one of a compound of the following formula (II); and a substituting radical in the formula is as defined in the specification. The dispersed black azo dye mixture can be used for dyeing micro-particle liquid state, dried power and grain state. When the dye disclosed by the invention is used for dyeing a polyester fiber material, a deep dark dyed texture with good performances of full color and cluster, good uniform dyeing performance and dispersity, sun resistance, washing resistance, sweat resistance and the like can be obtained through adjusting the ratios of different components.

Description

a technical field [0001] The invention relates to a disperse black azo dye mixture and a preparation method thereof, belonging to the technical field of chemical material preparation. Two background technology [0002] Dispersed azo dyes (English name: azo dyes) refer to a class of organic compounds that are connected to aryl groups at both ends of the azo group. and printing. This type of dye has the advantages of bright color, excellent fastness, and a wide variety of colors. Among them, disperse black azo dyes are widely used, but single-component disperse black dyes often have disadvantages such as deep dyeing, insufficient lifting power, and poor fastness. Especially when used for fabric printing, it will cause serious staining on white backgrounds. . [0003] At present, the methods of public reports about performance improvement at home and abroad include: U.S. Patent US6159249, Korean Patent KR0156834, KR95029349, KR2000060609, Taiwan Patent TW444047B, Chinese Pat...
