以“防伪标记”作为添加剂的新型喷墨墨水的研究

Novel Digital Printing Ink-Jet Inks with "Antifraud Markers" Used as Additives

摘译本文采用两种二苯乙烯衍生物——Kahablanc APU（C.I荧光增白剂220）和Kahablanc BA（C.I荧光增白剂113）用作防伪标记。将它们按不同的比例添加到水性喷墨墨水中。为了评估墨水的稳定性以及荧光增白剂与墨水其他成分的相容性,将制备的样品放置90天,测试其表面张力、pH值、黏度以及电导率。然后,将制备的墨水打印在聚酯（涤纶,PES）和聚酰胺（锦纶,PA）基材上，对样品的色牢度和颜色属性进行测量。

Author KARANIKAS E K, NIKOLAIDIS N F, TSATSARONI E G Department of Industrial Chemistry and Chemical Technology, School of Chemistry, Aristotle University of Thessaloniki, GR54124, Thessaloniki, Greece Abstract Two stilbene derivatives, Kahablanc APU （C. I Fluorescent Brightener 220） and Kahablanc BA （C. I Fluorescent Brightener 113） were used as possible ＂antifraud markers＂ . These were added in several amounts in water- based disperse ink -jet inks. The surface tension, pH, viscosity and conductivity of the formulations prepared were monitored over a period of 90 days in order to estimate the ink stability and the compatibility of the ＂antifraud＂ active agents with the ink constitu- ents. The inks were used for ink -jet printing of polyester and polyamide samples. Fastness and colour properties of the samples were measured.
