Abstract

Disclosed is high temperature resistant thermosensitive paper, a precoating is applied on the original thermosensitive paper; hollow ball resin is added in the precoating paint, a chromogenic layer is applied on the paper with the precoating; and a protective layer is applied on the paper with the chromogenic layer. The chromogenic layer comprises leuco dye, oxidant, sensitizer, lubricant, adhesive, filling calcining soil and anti-aging preparation. The protective layer is acrylamide and epichlorohydrin. In the novel thermosensitive paper process, color development occurs at 180 DEG C, and the bottom color occurs at 150 DEG C so as to solve the problem that common thermosensitive paper does not resist high temperature.

Description

Technical field [0001] The invention relates to a thermal paper, in particular to a high temperature resistant thermal paper. Background technique [0002] Thermal paper is widely used in logistics, labels, supermarket cooked food, etc. Some fields require thermal paper to have high temperature resistance, but currently domestically produced thermal paper has reached a high color density at 90 degrees Celsius, and Under the condition of 60 degrees Celsius, there is a background color. The barcode printed on thermal paper will show color at high temperature, resulting in illegible handwriting, and the barcode scanner cannot recognize the shortcomings, and it does not have the conditions for high temperature resistance. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing thermal paper that is not resistant to high temperature and provide a high temperature resistant thermal paper. [0004] To so...
