Background
With the rapid development of the inkjet ink market, in the field of digital inkjet printing, currently used inkjet inks include solvent-based inks, UV light-curable inks, and water-based inks. With the increasing rise of environmental protection call, solvent-based ink gradually exits the market due to environmental protection problems such as high VOCs volatilization and the like; the UV photocuring ink solves the problems of high VOCs and rapid curing, but has the defects of large monomer odor and strong irritation, and small molecular photoinitiator fragments remained after curing are easy to migrate to the surface of a curing film to cause pollution; the water-based ink is safe and environment-friendly due to the fact that water is used as a solvent or a dispersing carrier, and has no pungent smell, so that the water-based ink is increasingly widely applied to the field of ink jet.
Aqueous inks can be classified into aqueous dye inks and aqueous pigment inks according to the type of colorant. Wherein, the water-based dye ink can be quickly decomposed and volatilized under the irradiation of ultraviolet light, so that the water-based dye ink is not suitable for outdoor use; the water-based pigment ink has the characteristic of good sun-proof performance, but the pigment particles cannot be well attached to a base material due to the fact that no chemical bonds are formed between the pigment particles and non-absorption printing media such as polyvinyl chloride used outdoors and the like to form strong molecular force, so that a finished product after printing is poor in friction resistance. Therefore, how to improve the printing effect of the aqueous pigment inkjet ink on the non-absorbent printing medium is one of the problems to be solved in the art.
