Problems solved by technology

[0005] In recent years, there have been many researches on water-based light-curable inks at home and abroad. For example, CN103526570A discloses a preparation method of UV-curable inkjet printing pigment inks. The inkjet printing inks obtained by it are smooth, bright in color, and solid in color The effect is good, but the photoinitiator used in this ink is a small molecule photoinitiator, which is easy to volatilize and migrate during storage, resulting in low photopolymerization efficiency, and the unreacted photoinitiator will also migrate after the ink is illuminated to the surface, causing fouling of the cured film
CN106189512A discloses a water-based UV ink for inkjet printing and a preparation method thereof. The prepared water-based UV inkjet ink is environmentally friendly, has good printing fluency, and ink has good adhesion and abrasion resistance after the substrate is cured. The product is stable in storage, yet, similar to CN103526570A, what it adopts is a small molecule water-based photoinitiator, which is prone to migration, and the water-based photoinitiator is usually expensive and is not suitable for industrial production
CN104927485A discloses a water-based UV ink for inkjet printing and a preparation method thereof. The water-based UV ink has fast curing speed, low curing temperature, short drying time and good quality of printed products, easy cleaning of nozzles, low energy consumption, no irritation and odor odor, does not pollute the environment, but it uses a mixture of water and alcohol as a diluent, alcohol volatilizes quickly, increases the emission of VOCs, poor environmental protection, and easily leads to problems such as unstable ink and easy precipitation of pigments
