Title:
PROCESS FOR MANUFACTURING PERMANENTLY ERASABLE ELECTROSTATIC STICKER
Document Type and Number:
WIPO Patent Application WO/2017/063264
Kind Code:
A1
Abstract:
A process for manufacturing a permanently erasable electrostatic sticker, wherein free radicals are formed on the surface of an electrostatic sticker by treating the electrostatic sticker with ultraviolet light, and when writing on the electrostatic sticker with a whiteboard marker, ink from the whiteboard marker cannot react with ink on the electrostatic sticker, such that the ink does not adhere to the electrostatic sticker and can be erased even after a long time. Therefore, the electrostatic sticker can be used repeatedly. In addition, the electrostatic sticker has an anti-fouling effect due to its smooth surface.
