Abstract

The present invention relates to ink producing technology, and is especially one kind of ink for jet printing and its preparation process. The ink for jet printing is prepared with colorant 9-22 wt%, diglycol 8-10 wt%, triethanolamine 0.035 -0.04 wt%, diethylene glycol butyl ether 6-8 wt%, polyvinylpyrrolidone 1.5-3 wt% and water for the rest. Its preparation process includes the steps of: mixing the components to form material liquid and sealing, filtering with a Buchner funnel, and sealing the filtrate as the product in plastic barrel.

Description

technical field [0001] The invention relates to an ink and a production process, in particular to an improvement on the structure of the inkjet printing ink and its preparation method. Background technique [0002] With the continuous development of computer technology and digital technology, inkjet printers have been accepted by more and more users as a very useful output device, and the penetration rate has also increased day by day, making family and office affairs more convenient and convenient. Efficient and standardized. At present, the mainstream in the inkjet market is dye-based ink, which has the characteristics of bright colors and high reduction rate, but its poor waterproof and light resistance limits its application to a certain extent. A Chinese patent discloses a black ink for inkjet printing and its preparation method (authorized announcement number: CN 1184269C). 0.1-5 parts 0.1-0.5 parts of auxiliary agent, 55-80 parts of deionized water, the mixed dye is...
