THE STUDY OF UV-PHOTOCHROMIC ANTI-COUNTERFEIT PAPER

The hydrophilicity, dispersity and minuteness of UV (ultraviolet)-photochromic special function materials and its retention and formation mechanisms in stock were comprehensively studied, and the retention mechanism of UV-photochromic fiber was also studied. In addition, according to the disadvantages of special function materials such as big grain, bad hydrophilicity, expensive price and so on, this paper displays our effects focused on the developing of anti-counterfeit pigments slurry system. Moreover, the properties and anti-counterfeit mechanism of the paper with different special function materials were researched by fluorescent spectrum.
