     Thermosensitive paper is also called thermal fax paper, thermalsensitive recording paper, thermal copy paper is called thermal carbon paper in Taiwan. Thermosensitive paper is a kind of processing paper, and its manufacturing principle is coating on high-quality base paper. A layer of "temperature-sensitive paint" (heat sensitive color changing layer). Although there are more than ten kinds of chemicals used in this color-changing layer, there are at least the following compounds: colorless dyes, which have a wide variety of dyes and are most commonly used fluorescent compounds; Developer accounts for less than 20%, commonly used are bisphenol and p-Hydroxybenzoic acid; Sensitizer accounts for less than 10%, including benzene sulfonic acid amide compounds; Filler accounts for less than 50%, commonly used is calcium carbonate(Particles); adhesive about 10% or less, such as polyvinyl acetate; Stabilizer, such as dibenzoyl p-phthalic acid; Lubricant, etc. Therefore, the process is difficult and the technical requirements are high.
