Study on Europium Polymeric Fluorescent Material and Paper-Based Screen Printing Fluorescent Security Ink

Abstract:

Screen printing fluorescent security inks can be widely applied in the field of anti-counterfeiting packaging and printing special. Paper-based screen printing fluorescence security ink was prepared by europium polymer fluorescent material as fluorescent agent, alkyd resin etc as links, meanwhile various additives were added. The performance of europium polymer was studied by IR, UV spectra, fluorescence spectra, and fluorescent security performance of ink were studied by fluorescence spectrophotometer, the results showed that the fluorescence emission spectrum was narrow, and had a main peak at 612nm and high fluorescence efficiency, so this ink had good fluorescence security performance. The fineness,viscosity,stability etc printability of the ink were studied by fineness gauge, viscosity meter, the test result showed that the ink had good printability, can be applied in the security printing process of screen printing.
