【摘要】 以合成的新型荧光剂2－（4－甲氧基苯基）－3，1－苯并嗪唑－4－酮为发色剂，通过反复实验确定较佳配比，研制出有机防伪荧光油墨。该油墨目视色为无色，紫外光照射则产生很强的蓝色荧光，可用于防伪印刷。更多还原

【Abstract】 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.更多还原
