【摘要】 网印荧光防伪油墨是一种可以广泛应用在防伪包装印刷领域的特种油墨。本文以合成的铕高分子荧光材料为荧光剂,以醇酸树脂等为连结料,添加各种助剂,制得纸基网印荧光防伪油墨。研究了铕高分子荧光材料红外光谱、紫外光谱和荧光光谱,油墨的荧光光谱,结果表明荧光发射光谱很窄,主峰在612nm处,该油墨具有很好的荧光防伪性能。并研究了该油墨的细度、粘度、耐抗性等,结果表明该油墨有良好的印刷适性,可以应用在丝网印刷的防伪印刷工艺中。更多还原

【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 added various additives.Studied the performance of europium polymer by IR,UV spectra,fluorescence spectra,and studied fluorescent security performance of ink 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.Studied the fineness,viscosity,stability etc printability of the ink 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.更多还原
