The reverse side of carbon paper is coated with an acid-base chromogenic agent, and its reverse side is coated with a transparent cryptic agent. Therefore, when the carbon paper overlaps, it will crack the microcapsules due to the working pressure of mechanical equipment. When the transparent cryptic agent overflows, it will meet with acid and color the hair, and then produce an image. Carbon paper can carry out multiple overlapping applications, and carbon paper is usually used as a document.
