The surface of the paper is coated with a solid-state mixture of dye and a suitable matrix; a combination of a fluoran leuco dye for example. 80×80 Thermal Paper. When the matrix is heated above its melting point, the dye reacts with the acid, shifts to its colored form, and the changed form is then conserved in a metastable state when the matrix solidifies back quickly enough. The reactant acid in thermal paper is often bisphenol A (BPA). Thermal Receipts Paper // Thermal Paper Rolls Wholesale

Usually, the coating will turn black when heated, but coatings that turn blue or red are sometimes used. While an open heat source, such as a flame, can discolor the paper, a fingernail swiped quickly across the paper will also generate enough heat from friction to produce a mark. Thermal Paper Rolls Wholesale

Brief Knowledge about Thermal Paper: Thermal Paper Rolls Wholesale

Multicolor thermal paper first became available in 1993 with the introduction of the Fuji Thermo-Autochrome (TA) system. This was followed in 2007 by Polaroid’s development of the Zink (“zero-ink”) system. Both of these methods rely on multi-layer coatings with three separate colorizing layers, with different methods used for independent activation of each layer. Thermal Printer Paper Rolls
