中文摘要:
      目的 制备环保、适用范围广的温变转色防伪油墨。方法 利用隐色染料(热敏黑)、显色剂(双酚A)及溶剂(十四醇)组成可逆温变转色复配物,然后用原位聚合法对复配物进行微胶囊包覆,最后将微胶囊加入UV连接料体系中制成可逆温变转色UV油墨,分析油墨的色度学特性。结果 当乳化转速为16 000 r/min、pH值为2~3、乳化温度为45 ℃、乳化时间为30~40 min时,微胶囊粒径较小,显色效果较好。对该可逆温变转色UV油墨样品进行CIE-Lab色度学特性分析,在整个加热/冷却循环后,温变转色油墨又回到初始明度值,油墨样品明度发生滞后现象,整个过程中样品的明度值形成一个闭环的回路。结论 该法制备的可逆温变转色油墨具有检测方便、变色效果明显等优点,在包装防伪印刷中具有广阔的应用前景。
英文摘要:
      The work aims to prepare the environmentally-friendly thermo-chromic anti-counterfeit ink with extensive application scope. The reversible thermo-chromatic compound was prepared with leuco dye (thermosensitive black), developer (Bisphenol A) and solvent (tetradecyl alcohol), and then the microcapsule was covered through in-situ polymerization. Finally, the microcapsules were added to UV system of binders to prepare the reversible thermo-chromic UV inks and analyze the colorimetric properties of ink. The microcapsule grain size was smaller and the color developing effect was better when the emulsification speed was 16 000 r/min, pH value of 2~3, emulsification temperature of 45 ℃ and emulsification time of 30~40 min. The CIE-Lab colorimetric properties of the reversible thermo-chromatic UV ink samples were analyzed. After the whole heating/cooling circle, the lightness (L*) of the ink was changed back to the original value and the lightness change of the ink was delayed. In the whole process, the lightness values of samples were formed as a closed loop. The reversible thermo-chromic ink prepared in such method characterized by convenient detection and significant color change effect, etc. has broad application prospects.
