synthesis of the uv curable anticounterfeiting ink based on waterbased urethane acrylate resin, modified with rhodamin b

Rhodamine b is modified (forming an unsaturated double bond) by adding ethylene diamine and glycidyl methacrylate in two steps, urethane acrylate resin based on the raw materials of isophorone diisocyanate, ptmg, hexafor 678, tegomer d3403 and hema was synthesized in two steps. in this study, the anti-counterfeiting ink will be synthesized by ultraviolet curing method. the result of fluorescence atomic emission spectroscopy test showed that the resin containing modified rhodamin increases the photoluminescence properties in water-based systems, modified rhodamin synthesized in urethane acrylate resin did not have any fluorescence radiation under normal conditions, while it has pink fluorescence radiation under uv light, this property makes rhodamine as the best candidate for using in anti-counterfeiting documents.
