Thermal paper offered through ReceiptRolls.com is a fine paper that contains a chemical which, when heated, changes color. This "ink" shows up whenever a paper roll runs through and is heated by a credit card terminal, cash register, or adding machine.
The surface of thermal paper contains a solid-state mixture of a matrix and a dye. As the matrix heats up to its melting point, the acid reacts with the dye, changes to colored form, and is preserved in metastable state as the matrix returns to a solid state rather quickly. Generally, the coating is made to turn black as it heats, though blue or red are other options. Open flame can cause discoloration, and the quick swipe of a fingernail across the surface of the paper can have enough friction to generate the heat necessary for producing a mark on the paper.
Most thermal papers have a topcoating to protect the image from fading when exposed to UV light, oils, water, lard, grease, fats, or plasticizers. The topcoating additionally focuses the thermal printhead's heat on the coating, lets flexographic printing inks better anchor to the paper, lessens the residue left on thermal printheads, and reduces printhead wear.
