The paper can be used in a plurality of overlapping ways and is used as a bill for multiple purposes; the carbonless copy paper is copy paper without using coloring wax. When multiple carbon-free copy papers are stacked together, a plurality of documents can be copied by direct printing or pen writing. The printing paper is convenient and clean, and can be made into a tooth hole type blank computer printing paper to realize efficient continuous printing and copying; the carbon-free carbon paper can be copied without being coated with wax, because the carbon-free carbon paper is coated with chemicals; the carbonless copy paper is divided into upper paper, middle paper and lower paper. The lower surfaces of the upper paper and the middle paper are coated with a certain chemical, and the upper surfaces of the middle paper and the lower paper are coated with another chemical. After the upper page, the middle page (6 pages can be avoided or even be available) and the lower page are combined in sequence, when the impact force of a printing needle or the pressure of a pen point is applied, two different medicines can meet to show a color trace, so that the aim of duplicating is fulfilled; the upper paper is conventionally called CB paper, and only one side of the upper paper is coated with CB medicines and called CB side; the lower page paper is conventionally called CF paper, and only one side of the lower page paper is coated with CF medicines and is called a CF side; the middle sheet is conventionally called CFB paper, and has a CF side coated on one side and a CB side coated on the other side.
