Description

technical field

[0001] A nano-pigment inkjet printing ink and a preparation method thereof relate to the fields of computer inkjet printing and color inkjet printing. technical background

[0002] With the development and popularization of digital technology, inkjet printing technology is widely used in various fields such as office document printing, outdoor advertising inkjet printing, digital photo printing, and textile inkjet printing. Inkjet printing ink is the key to inkjet printing technology, and dye ink is currently the main application. Dye ink is easy to prepare, but its light fastness is poor, it is easy to fade under light, and it is difficult to meet the long-term preservation requirements of outdoor advertisements, important archives and documents. These disadvantages of dye inks limit the development of inkjet printing technology.

[0003] Compared with dye ink, the light fastness and water fastness of water-based pigment ink are greatly improved. At prese...
