The surface of the thermal paper is saturated with a mixture of a dye and few chemicals. When the paper is exposed to heat the dye reacts with the acid and then the paper changes its color. There is also a protective coating on top of the thermal paper so that it does not fade due to UV rays, water and oil and does not cause much damage to it. This layer also protects the paper from getting messed by the printer heat.
