Example Embodiment

[0037] Example 1

[0038] The diazonium component dissolving pot is sequentially added with 190g of water, 75.11g of 2-bromo-4-carboxymethylsulfonylaniline with a purity of 97.5%, and sodium hydroxide with a purity of 96% to neutralize and dissolve to the complete solution. 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 to cool to 0~1℃, then the diazonium component liquid is obtained, and the diazonium component liquid is transported to the high level of the diazonium liquid Tank; add 125g water, 58.92g m-acetamido N, N dipropyl aniline with a purity of 99%, and 25 ml hydrochloric acid with a concentration of 36.5% to the coupling component dissolving pot, and wait for the m-acetamido N, N dipropyl aniline to dissolve After obtaining the coupling component liquid, the coupling component liquid is transported to the coupling reaction kettle; another part of 36.5% hydrochloric acid 2...

Example Embodiment

[0041] Example 2

[0042] Using the 3% liquid water-soluble disperse dye prepared in Example 1 as the ink for inkjet printer, after printing, the writing is uniform, and after the dye is deposited on the printing paper, the dye will not dissolve twice. Drop water droplets on the printed paper to prevent ink spreading.

Example Embodiment

[0043] Example 3

[0044] Using the 3% liquid water-soluble disperse dye prepared in Example 1, add 0.5% of the total mass of the ink ammonia, 1% of the total mass of the ink ethylene glycol dimethyl ether, and 0.1% of the total mass of the ink JFC dispersant, stir and mix After uniformity, as an inkjet printer ink, the writing will be uniform after printing. After the dye is precipitated on the printing paper, the dye will not dissolve twice. Drop water droplets on the printed paper, without causing ink diffusion.

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...
