Introduction of Carbonless Paper

Carbonless paper is a kind of chemical type pressure-sensitive recording paper, which does not use colored pigment; the number of layers is also called ply, for example, the 3 ply of paper is called 3 layers of paper. The 3 ply carbonless paper receipt can be divided into coated back paper, coated front and back paper and coated front paper. The coated back paper(CB for short), the back of the which is coated with microcapsules containing force sensing pigment oil; the coated front and back paper(CFB for short), the front of which is coated with a chromogenic agent. Besides, the back of the paper is coated with microcapsules containing force sensing pigment oil; the coated front paper (CF for short), the surface of which is only coated with a chromogenic agent. When in the process of printing, press the printing needle on the paper surface to achieve the color rendering effect by the principle of the chemical reaction between the chromophore in the microcapsule and the acid clay in the coloring agent layer.

To produce high-quality carbonless copy paper needs high-quality coating base paper. What's more, the selection and match of CB coatings and its components are also very important. Only by attaching importance to the development and application of CB and CF coatings, optimizing the formula of CB coatings and CF coatings, and carefully operating in the process of production, high-quality carbonless paper can be produced.
