Zhang Wenguan; Yang Lianming; Wang Wenguang; Jiang Hejin (Beijing Institute of Printing)
In this paper, a new organic fluorescent reagent as 2- (4- methoxyphenyl)-3, 1-ben-zoxazin-4-one has been synthesized. The various result show that the organic falsification-resistent fluorescent ink containing this substance is more satisfactory. This kind of invisible ink exhibites a strong blue flourescene when irradiated with ultraviolet light, so it is suitable for falsification-resistent printing.
