Thermal paper is soaked in the solid- state fusion of matrix and dye which is further a combination of fluoranleuco dye and an octadecylphosphonic acid. When this mixture is heated to a certain temperature, it usually reacts with the acid and transforms to the colored form and the changed state is then preserved in metastable form. After that paper rolls are protected with the top coating in order to reduce fading of the image printed on the paper when exposed to water, lard, grease, fats, plasticizers, UV lights and similar agents.
