Abstract: |
By repeating experiments, the preparation technological conditions of microcapsule were determined considering their respective optimal compositions of the core and shell of microcapsule, and other factors. And some properties of reversible thermochromic materials and microcapsules were studied including the resisting capabilities of fatigue and oxidation, the stability to chemical ambiences such as acid, alkali and solvents, etc. By experiment equipment, this paper prepared the reversible thermochromism material in offset printing ink, and discussed the printability of reversible thermochromism off-set printing ink. By spector photometer, measured the L a b value, chromatism, and anti-counterfeiting properties of off-set printing ink of reversible thermochromism ink under off-set printing pattern. This paper has theoretical direction function in anti-forgery ink of reversible thermochromism material.
