Abstract

A multi-color combined ink for ink-jet printer features that the ink for each color contains colouring agent, molecule-induced phase separater, levelling disperser, chelating agent, pH regulator, and the defoaming, antibacterial and drying additives. Said molecule-induced phase-separater is a water-soluble high-molecular polymer for preventing the osmosis between adjacent colors to obtain high-quality color graphics. Its advantages are low cost, no corrosion, poison and environmental pollution, and high resistance to water.

Description

technical field [0001] The invention relates to the ink for inkjet printers, especially the technical field of color inkjet printing. Background technique [0002] The rapid development of computers and matching printers and other equipment has made all office affairs more efficient, convenient and standardized. In the printer, the inkjet printer uses the ink droplets in the printer ink cartridge, under the control of the computer, to spray them out through its nozzles in a specific order, and deposit them on the printing medium to form text and images. Compared with laser printers, its price is lower, compared with dot matrix printers, its noise is lower, and high-quality color graphics and image output can be obtained. Its obvious advantages make inkjet printers develop rapidly. Especially with the development of the digital camera market, the requirement for color image output has increased, making inkjet printers a substitute for other printers. Regardless of whether i...
