Problems solved by technology

However, the dye varieties provided by this patent cannot meet the actual needs of the market. Many varieties still need to be improved in terms of dyeing efficiency and production cost, and the variety of designs and colors is not rich enough.
[0006] Especially red as a widely used color, red dyes with different characteristic wavelengths have their uses, and the current varieties can not meet the needs of actual use

Embodiment 1

[0038]Add 190g of water, 75.11g of 2-bromo-4-carboxymethanesulfonylaniline with a purity of 97.5%, and sodium hydroxide with a purity of 96% to the diazo component dissolving pot in order to neutralize and dissolve until fully dissolved. The amount of sodium hydroxide added makes the solution pH = 7~7.5, then add 58.51ml of sodium nitrite with a concentration of 29.48g / 100ml, add ice and cool to 0~1°C to obtain the diazo component liquid, and transport the diazo component liquid to the high level of the diazo liquid Groove; Add water 125g, purity 99% m-acetamido N, N dipropylaniline 58.92g, concentration 36.5% hydrochloric acid 25ml successively in the coupling component dissolving pot, wait for m-acetamido N, N dipropylaniline to dissolve Finally, the coupling component liquid is obtained, and the coupling component liquid is transported to the coupling reaction kettle; another part of 36.5% hydrochloric acid 20.3ml is diluted to 20% and transported to the dilute hydrochloric ...

Embodiment 2

[0042] Use the 3% liquid water-soluble disperse dye that embodiment 1 prepares as the inkjet printer ink, after printing, handwriting is even, after separating out dyestuff on printing paper, dyestuff can not be dissolved again. Drops of water are added to the printed paper without ink spreading.

Embodiment 3

[0044] Use the 3% liquid water-soluble disperse dye of embodiment 1 preparation, add the ammoniacal liquor of 0.5% of ink gross mass, the ethylene glycol dimethyl ether of ink gross mass 1%, the JFC dispersant of ink gross mass 0.1%, stir and mix After uniformity, as an inkjet printer ink, after printing, the handwriting is uniform, and the dye will not be dissolved again after the dye is precipitated on the printing paper. Drops of water are added to the printed paper without ink spreading.

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...
