Abstract:

“Water-jet printing” has attracted wide attention owing to its green process and environmental friendliness. Therefore, it is significant for industrial preparation of water-jet rewritable paper. In this work, taking a hydrochromic dye indole [2,1-b] oxazolidine(TM) for example, the industrial preparation process of water-jet rewritable paper based on polyethylene terephthalate(PET) instead of filter paper was explored in detail and successfully obtained via screening of surfactant, adjusting the amount of dye, and modulating coating thickness. The paper prepared via the optimized process exhibits great rewritable performance. Furthermore, successful small-scale production of this paper indicates that the optimized process can be widely applied in industrial production.

Key words: water-jet printing, rewriting, hydrochromism, coating, industrial preparation process
