Abstract

The invention relates to a blue azo dye composition and application thereof. The blue azo dye composition comprises at least two compounds shown as a formula (I). The blue azo dye composition can be applied to dyeing and printing hydrophobic materials or blended materials with hydrophobic materials. The blue azo dye composition and the application have the advantages that the color fastness to sunlight and the fastness to rubbing can be obviously enhanced by the aid of the blue azo dye composition, and particularly, the blue azo dye composition is excellent in fastness to acid and alkali perspiration and quite suitable for dyeing sportswear fabrics next to skin.

Description

technical field [0001] The invention belongs to the field of disperse dyes, in particular to a blue azo dye composition and its application. Background technique [0002] Azo dyes have been used for dyeing hydrophobic fiber materials for a long time, and there are more and more blends of dyes. However, with the expansion of the application of such dyes, the existing dyes still have insufficient application properties such as lifting power and color fastness. Therefore, a new azo dye is continued to be developed to meet the new needs of the market. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a blue azo dye composition and its application. The azo dye composition can significantly improve the color fastness to sunlight and the fastness to rubbing. It is particularly worth mentioning that The present invention also has excellent fastness to acid sweat and alkali sweat, and is very suitable for dyeing close-fitt...
