Carbonless Paper Sheet

Flat-sheet carbonless copy paper is a kind of invisible copy paper, which has the function of direct copy and direct color development. The color development of the paper is mainly caused by the force-sensitive pigment and the oil solution in the microcapsules to overflow and contact with the color developer under the action of external force to cause a dyeing reaction, thereby playing the role of copying. Mainly used for printing, copying, etc. It is a novel copy paper,

There are two kinds of coatings in flat-sheet carbonless copy paper, one is the CF layer containing the developer, and the other is the CB layer containing the developer. The chromogen is a special leuco dye that can be dissolved in a non-volatile carrier oil. Even the copy paper is constantly improving. The current flat-sheet carbonless copy paper is more convenient. It can be printed directly on the back paper without having to prepare more copy paper. Therefore, when the current copy paper is used, attention should be paid to isolation and protection, and the hard paper should be stuck in places where it is not necessary to print, so as to avoid unnecessary trouble.

The impact pressure of strong writing and printing can crush the microcapsules, causing the leuco dye solution to flow out and contact with the developer, and a chemical reaction occurs to present colored graphics and text, thereby achieving the purpose of copying. Carbonless copy paper is divided into five types according to the color of the paper: red, yellow, green, blue, and white; according to the color traces it appears, it can be divided into blue, yellow, orange, black, red and other colors; it can be divided into rolls according to specifications Paper and flat paper.
