Abstract

The invention relates to a water-based pigment ink-jet ink containing a core-shell amphiphilic-type polymer microsphere emulsion. The water-based pigment ink-jet ink comprises the following components in parts by weight: 5 to 40 parts of core-shell amphiphilic-type polymer microsphere emulsion, 5 to 40 parts of water-based pigment paste, 1 to 30 parts of organic cosolvent, 20 to 60 parts of main solvent and 0.5 to 2 parts of surfactant. According to the water-based pigment ink-jet ink, the wetting spreadability of the water-based pigment ink on plain paper during ink-jet printing is effectively improved; and the rapid low-temperature drying of the ink-jet ink on the surface of a basic material and the good adhesion of the ink-jet ink after the film forming are realized. Thus, a good picture effect on the plain paper in the ink-jet printing manner can be realized while the aftertreatment such as the additional arrangement of a heating device on a printer or the heating of a printed picture and the like is not required. Thus, the water-based pigment ink-jet ink provided by the invention has a high market application value.

Description

technical field [0001] The invention relates to a water-based pigment ink-jet ink, in particular to a water-based pigment ink-jet ink containing a core-shell amphiphilic polymer microsphere emulsion. Background technique [0002] When water-based pigment ink is applied to inkjet printing on plain paper, it is prone to ink accumulation, slow drying, and water resistance. The commonly used solution at present is to heat the printing medium while printing, that is, add a heating device to the printer, so that the printing medium has a higher temperature during printing, which can significantly improve the printing quality. But this changes the original structure of the printer, and the cost will be greatly increased. [0003] Traditional polymer emulsions are used as film-forming resins in inkjet inks to enhance the adhesion of inks to substrate surfaces. In the water-based system, the main solvent of the polymer emulsion is water, and in order to ensure the stable existence ...
