The second type is double-ply, known as the Two-sheet type. This is composed of two polyester bases, one being coated with a layer of micro-encapsulated color-forming material and the other with a layer of color-developing material. The two bases are used together, with the coated sides facing each other. When pressure is applied, the microcapsules holding the color-forming material are broken, and this reacts with the color-developing material on the film.
