印制人民币时,采用光变色防伪油墨所需的高纯度氟化镁光学镀膜材料依赖进口的局面将会改变。不久前,中科院长春光机与物理研究所的“奥普”公司成功研制出了这种适用于纸币防伪、完全可替代进口的特种光学镀膜材料。有关专家对该成果作出鉴定
When the renminbi is printed, the situation in which high-purity magnesium fluoride optical coating materials required for the use of photochromic anti-counterfeiting inks depends on imports will change. Not long ago, the “Aopu” company of the Changchun Institute of Optics and Physics, Chinese Academy of Sciences successfully developed this kind of special optical coating material that is suitable for banknote anti-counterfeiting and is completely replaceable. Experts appraised the result
