Take triple NCR receipt, it can be divided into the paper, the paper, the next paper. On paper, also known as the back-coated paper (codenamed CB, namely Coated Back), on the back of the paper is coated with microcapsules containing a force-sensitive pigment oil; the paper, also known as reverse double-coated paper (codenamed CFB, namely Coated Front and Back), the front of the paper is coated with a reagent, the back is coated with microcapsules containing a force-sensitive pigment oil; paper, also known under the top coat paper (codenamed CF, namely Coated Front) copy paper, paper coated with a reagent only. Since color paper (code SC, namely Self-Contained) is in the back of the paper is coated layer of microcapsules containing carbon Hunan force sensitive pigment oil painted front chromogenic reagent and force-sensitive microcapsules containing pigment oil. CF carbonless paper coatings main dyeing auxiliaries: suds suppressors, lubricants and dispersing agents. Suds suppressors inhibit and prevent foam coating paper "fish-eye" generation. NCR may reduce lubricant powder out and cracking and peeling phenomenon problems caused when folded. Dispersants can reduce the viscosity of the coating Hubei carbon paper, prevent agglomeration, caking and settling. CF coating pigment for mainly kaolin and calcium carbonate. 2um particle size kaolin require up to 70% less; calcium carbonate is precipitated calcium carbonate, particle size 0.1-1um. Calcium carbonate can increase paper opacity, whiteness and ink absorbency Shandong carbon paper, but the use of calcium carbonate as well as easy to be dried more adhesive (large surface area), and therefore rarely used alone in the actual production, the general mixed with kaolin used in an amount of 20% -70% kaolin, it is a good carbonless paper dyeing.
