preparation example Construction

[0026] The preparation method of structural formula (I-1): 1,4-diaminoanthraquinone is chlorinated, sulfonated, cyanided, dehydrated and ring-closed, and then condensed with methylamine.

[0027] The preparation method of structural formula (I-2): 1,4-diaminoanthraquinone is chlorinated, sulfonated, cyanided, dehydrated and ring-closed, and then condensed with ethylamine.

[0028] The preparation method of structural formula (I-3): 1,4-diaminoanthraquinone is chlorinated, sulfonated, cyanided, dehydrated and ring-closed, and then condensed with propylamine.

[0029] The preparation method of structural formula (I-4): 1,4-diaminoanthraquinone is chlorinated, sulfonated, cyanided, dehydrated and ring-closed, and then condensed with isopropylamine.

[0030] Structural formula (I-5) is C.I. Disperse Blue 60.

Abstract

The invention discloses a disperse blue dye composition, mainly comprising a component A and a component B, wherein the component A is at least one of compounds shown by a formula (I), and the component B is a compound shown by a formula (II). The invention also discloses a disperse dye comprising the dye composition and a preparation method and an application of the disperse dye. The disperse dye disclosed by the invention has the advantages of bright color, good deep dyeing property, high strength, good lifting power, good sublimation fastness, excellent fastness to saliva and the like; in particular, the disperse dye has a good printing effect; the printed fabric is clear in outline, thick and bright in color, and better than an expensive C.I. disperse blue 60 dye finished product in dyeing intensity; as a result, the usage amount of the dye can be greatly saved and the dyeing cost also can be saved.

Description

technical field [0001] The invention belongs to the technical field of organic dye chemical industry, and in particular relates to a disperse blue dye composition, disperse dye, preparation method and application. Background technique [0002] As we all know, C.I. Disperse Blue 60 has been recognized by printing and dyeing enterprises for its bright shade and good dyeing fastness. However, its price is high and its dyeing depth is average. It can only be used for dyeing light colors. Too light, basically can not be used for printing. And as the amount of dyes increases, the fastnesses decrease simultaneously, and how to overcome these weaknesses, improve the overall performance of dyes and expand the scope of use of dyes is an important research project for the dye industry. [0003] In order to solve the above technical problems, the patent document with the application number CN 201110457474.5 discloses a blue disperse dye, which mainly consists of the following component...
