Embodiment 1

[0042] synthetic target

[0043]

[0044] Raw materials include p-carboxymethanesulfonylaniline, ethylbenzylaniline, sodium nitrite, hydrochloric acid, ethanol, etc., and sequentially add 38 g of water, 11.32 g of carboxymethylsulfonylaniline with a purity of 95%, and a concentration of 36.5 % hydrochloric acid 9ml, after the carboxymethylsulfonylaniline is completely dissolved, the jacket is passed through frozen brine, and 11.7ml of sodium nitrite solution with a concentration of 29.48g / 100ml is added at 0°C and normal pressure to carry out the diazotization reaction. After the reaction, Diazonium salt solution, diazotization reaction time is 3 minutes, use KI-starch test paper to control the end point to be slightly blue, continue to stir for 2 minutes, then add the diazonium solution to the coupling reaction kettle; 25ml of alcohol, 10.63g of ethylbenzylaniline with a purity of 99.4%, completely add to the coupling reaction kettle within 1 hour after dissolution; the co...

Embodiment 2

[0047] 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

[0049] Use the 3% liquid water-soluble disperse dye that embodiment 1 prepares, 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 application of orange temporarily water-soluble disperse dye in preparation of inkjet printing ink. The general formula of the structure is shown in the specification, wherein R1 is -C2H4CN or -CH2C6H5. The application method comprises the following steps: directly taking the standardized liquid water-soluble disperse dye as the inkjet printer ink, or adding stabilizer, surfactant and dispersant into ink to obtain the inkjet printer ink. According to the inkjet printer ink prepared in the invention, after the dye is separated out on the printing paper, the dye is not dissolved for the second time, and ink marks do not diffuse when the dye encounters water; and the technical effect of printing is effectively protected.

Description

[0001] technical field [0002] The invention relates to a dye technology, in particular to the application of an orange water-temporarily soluble disperse dye in the preparation of ink-jet printing ink. 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] The Chinese patent application number 95110173 introduces a water-temporarily so...
