There are two types of coatings in the NCR: CF layer and the layer containing a chromogenic agent CB containing hair color agent. Coloring agent is a special kind of leuco dye, is dissolved in a non-volatile carrier oil, 3 ~ 7μm was encapsulated microcapsules. Impact pressure may force the writing and printing of the microcapsules crushed, so colorless dye solution out of contact with the chromogenic agent, a chemical reaction occurs colored graphic presentation Shandong Paper, so as to achieve reproducible. NCR divided by quantitative 45g / m2CB paper, 47g / m2CF paper and 52g / m2CFB paper; divided according to the color of paper red, yellow, green, blue, white five; by appearing blue color trace points, yellow, orange, black, red and other colors.
