Non-carbon copy paper (No Carbon Required paper) One side of the paper is coated with microcapsules (CB), which contain pigments, and the other side is coated with a developer (CF side). When used, the CB side and the CF side must be in contact with each other. Correspondingly, when the paper is pressed, the microcapsules on the CB side rupture, the pigment escapes and reacts with the developer on the CF side to develop color. This principle is used to achieve the replication effect. Generally, NCR can be divided into three types: top paper, middle paper, and bottom paper, which can be prepared according to the number of sheets required for copying. 2.
