Abstract

The invention discloses a red temporary water-soluble disperse dye and a manufacturing method and use thereof. The structure formula of the dye is shown below. The chromatographic peak of the dye disclosed by the invention is wide, the dyeing exhaust property of the dye is better, the raffinate is almost colorless, the molar extinction coefficient of the dye is high, and the color of the dye is bright; the yield of the dye is close to a theoretical value, and waste water treatment is convenient; and color fastness to light and color fastness to washing are greatly improved than before. The dye can be used for preparing ink for ink-jet printers. When the ink is used, the dye separated out on printing paper does not dissolve again, nor disperse upon contact with water, and thus, the application range of the ink-jet printers is expanded.

Description

[0001] technical field

[0002] The invention relates to a dye technology, in particular to a red water-soluble disperse dye and its preparation method and application. Background technique

[0003] Most of the fuels currently on the market are oil-soluble dyes. Water-soluble disperse dyes are mainly used for dyeing and printing polyester fibers. In application, it can save the ordinary disperse dye sanding post-treatment process and dispersant, save energy, improve labor productivity, and can be mixed with reactive dyes for polyester / cotton one-bath dyeing, and the application is very convenient. After 20 years of research, the color spectrum of this type of dye has been relatively rich. However, the existing varieties on the market cannot meet the actual needs, especially the requirements for more varieties of patterns and higher dyeing efficiency.

[0004] Application number is that the Chinese patent of 95110173 has introduced a kind of water temporarily soluble blue d...
