摘　　要：目的获得一种透明荧光防伪印油的优选配方和制备步骤,并研究影响其物理指标和防伪指标的因素。方法采用自制稀土基荧光粉,制备了一系列用于塑料薄膜的透明荧光防伪印油样品,通过研究树脂、荧光粉、芥酸酰胺(EA)和370M质量分数对印油印记物理指标——干燥性、抗反粘、附着牢度和防伪指标荧光性的影响,筛选出一种优化配方,并与同类某进口产品(市场样)进行比较研究。结果树脂分子有助于提高荧光粉的发光强度;EA和370M有助于改善3个物理指标;EA和370M最优质量分数为1.5%。所得优选印油比市场样干燥快25%,负重抗反粘性比市场样提高了48%,附着牢度与市场样接近;印记透明,隐蔽性强,具有完全不同于市场样的防伪特征,表现出对检测波长的选择性,防伪力度优于市场样,耐光性5级,远高于市场样1级。结论所得优选印油的各项指标综合表现优于同类进口产品,可望用于烟、酒和化妆品等高端产品外层的透明塑料薄膜上进行防伪。To obtain an optimum formula and steps of a transparent fluorescent anti-counterfeiting stamp-ink and study factors affecting its physical and anti-counterfeiting indicators. A series of anti-counterfeiting stamp-inks for plastic films were prepared with self-made fluorescent powders based on rare earth. The effects of the contents of resin, fluorescent powders（EA） and 370 M on the drying, blocking resistance, adhesion and fluorescence properties of imprinted samples were investigated in order to screen out an optimum formula whose properties were compared with those of a imported product（market sample）. The resin molecule could increase the intensity of luminescent powders, while EA and 370 M could improve the three physical properties. The best mass fraction of EA and 370 M was 1.5%. The drying rate of the optimum stamp-ink was 25% faster than that of the counterpart, while its blocking resistance was 48% higher than that of the counterpart. Its adhesion strength was similar to that of the counterpart. The imprinted sample was transparent. It had high invisibility and anti-counterfeiting property very different to that of the counterpart. It showed the selection on the measure wavelength. Its anti-counterfeiting property was also superior to that of the counterpart. Its grade of light resistance was V which was I grade higher than that of the counterpart. The overall performance of the optimum formula is better than the counterpart, which might apply to the transparent plastic films outside packing materials of cigarette, alcohol and cosmetics to guard against falsification.
