Thermal paper is also called thermal fax paper, thermal recording paper, thermal copy paper, and in Taiwan it is called thermal carbon paper. Thermal paper is a kind of processed paper. Its manufacturing principle is to coat a layer of "thermal coating" (thermal color-changing layer) on high-quality base paper. Although there are more than a dozen chemicals used in this color-changing layer, there are at least the following compounds: colorless dyes, which are of a wide variety, and the most commonly used are fluorescent compounds; color developers account for less than 20%; sensitizers account for less than 10%, including benzenesulfonic acid amide compounds; fillers account for less than 50%, commonly used calcium (microparticles); adhesives account for less than 10%, stabilizers, such as diphenyl terephthalate, etc. Therefore, the process is difficult and the technical requirements are high.
