磁性油墨的研究进展

Development of the Magnetic Ink

磁性防伪油墨具有外观色深、检测仪器简单、防伪效果突出等优点，是一种重要的特种防伪油墨。

Magnetic ink is a kind of important special anti-forgery ink , with dark-color appearance , simple testing equipment , remarkable anti-counterfeiting .

尖晶石型铁氧体是最常用的磁性防伪油墨颜料，因此，制备高性能的尖晶石型铁氧体磁性粒子是获得高质量磁性油墨的关键。

Spinel ferrite is the most common magnetic ink pigments . Preparation of high-performance ferrite pigments is the key to prepare magnetic ink .

首次指出：在今后的研究中应该采用纳米级的磁性颜料和复合磁性颜料，选用合成树脂作为连接料，并应重点研究添加料与磁性油墨性能的关系。

The study direction of magnetic ink was discussed , and firstly pointing out that the nano , composite magnetic pigment , the synthetic resin , the connection of the joint material and the magnetic ink should be used and emphasized in the future research .
