Thermal roll paper
Thermal paper is also called thermal fax paper, thermal recording paper, thermal Copy Paper, and thermal copy paper in Taiwan. Thermal paper is a kind of processed paper, and its manufacturing principle is to coat a layer of "heat sensitive paint" (heat sensitive color change layer) on high-quality base paper.
Although there are more than a dozen chemicals used in this color change layer, there are at least the following compounds: leuco dyes, the dyes are of a wide variety, the most commonly used are fluorescent compounds; the color developer accounts for less than 20%, and the commonly used are double Phenol, p-hydroxybenzoic acid; sensitizers account for less than 10%, which contains benzenesulfonic acid amide compounds; fillers account for less than 50%, commonly used calcium carbonate (fine particles); adhesives account for less than 10%, Such as polyvinyl acetate; stabilizers, such as dibenzoyl terephthalate; lubricants, etc.
Therefore, the process is difficult and the technical requirements are high.
Thermal paper is generally sold in the form of rolls, generally 80mm×Φ60mm, 57mm×Φ50mm and other specifications are the most common. The first number indicates the width of the paper roll, and the back is the diameter. The general error of the width of 1, 2mm will not affect the use, because Printers generally can`t print on the edge
