In the field of packaging printing, UV inks have long been used, mainly for surface treatment of offset prints, to increase the abrasion resistance of the surface ink layer. Not only can show visual characteristics of matte, frosting and the like, but also can realize various superior physical properties of moisture resistance, flame retardance, wear resistance and the like. As one of them, flame retardant UV inks are generally used in cases where the storage environment or the use environment is relatively extreme, or in cases where long-term use is required. For example, in the aspect of transport packaging, the flame-retardant ink is often applied to corrugated cartons, which greatly facilitates transportation and storage and is extremely beneficial in harsh environmental conditions. In food packaging, there are many cases where the packaging is heated at high temperatures, and flame-retardant inks are also used to ensure safety of use. And flame retardant UV inks are also used in label printing, which are stable in the face of high temperatures and long periods of direct exposure to light.
However, most of the flame-retardant UV inks widely used in the market currently have the problems of large odor, environmental pollution, short service life and the like, and the application range and development of the inks are limited to a great extent.
