Abstract

The invention discloses ultraviolet-curing water-based inkjet ink. The ultraviolet-curing water-based inkjet ink at least comprises the following components in percentage by weight: 1%-12% of nanometer pigment / water-soluble pigment, 1%-5% of dispersing agent, 1%-15% of UV (Ultraviolet)-curing modified polyurethane resin emulsion (solid content), 1%-10% of photoinitiators, 20%-50% of reactive diluents, 5%-25% of humectants, 5%-15% of penetrating agents, 0%-2% of surfactants, 0%-2% of pH regulators, 0.1%-0.5% of sterilization preservative, and the balance of deionized water. The ultraviolet-curing water-based inkjet ink is characterized in that the ink has excellent storage stability and printing fluency; the ink has excellent performances including water resistance, light resistance, solvent resistance, scratch resistance, ageing resistance, high-low temperature resistance, high brightness, good adhesive strength and quick curing speed, is suitable for various printers to print various uncoated and nonprinting coating media, hydrophobic and oily media, and is wide in application area.

Description

technical field [0001] The invention relates to an ink-jet ink, in particular to a UV-cured water-based ink-jet ink. Background technique [0002] Due to its strong advantages, inkjet printing has made significant progress through nearly 30 years of development. It has been used in digital printing, digital printing, digital images, office documents, outdoor inkjet printing, surface decoration and other fields, providing great support for human production and life. convenient. Water-based inkjet ink is favored by people for its environmental protection and wide application range. [0003] As usage increases and scope expands, disadvantages of water-based inkjet inks are discovered. For example, if the printer is not used for a long time, it is easy to block the nozzle; the ink on the paper is not resistant to scratches, has no luster, and the color is dull; it cannot print coated paper, plastic, glass, etc.; it cannot print hydrophobic and oily media; paper needs to be spe...
