The legal effect of the formal documents have now invoices, contracts, treaties, etc., have all spend the NCR. NCR is a hidden color copy paper, a direct replication, direct color features. Its color is mainly: the external force carbonless paper prices flat, so the force-sensitive microcapsule pigment and oil spill occurred after contact with a solution of reagent staining reaction, and thus play a role in replication. Mainly used for multipart forms, bills, continuous fiscal tickets, tickets and other general business wealth. NCR can be divided according to the specifications of the web (rools) Peace paperboard (sheets). Web widths from 160mm to 1940mm flat carbon paper wholesale, flat paper sizes from 420mm * 530mm to 1420mm * 1420mm. NCR production techniques of the past few years the country has successfully developed a resin-modified alkyl salicylate zinc reagent, while maintaining excellent speed and color based on the color optical density greatly improved lightfastness, such light resistance alkyl zinc salicylate resin has been applied in a number of manufacturers. Carbonless CF paper of the main component of the adhesive coating has a PVA, styrene-butadiene latex, such as modified starch. Although the maximum bond strength PVC, styrene-butadiene latex is 1.5-2 times, 3-4 times starch, but because PVA sensitive to water, strong film (will affect the color effect NCR), the high cost of the plate Carbonless Paper Company, susceptible to acids, alkalis, there is rheology deterioration problems at high speeds without using a separate shear. Styrene-butadiene latex adhesive force and good water resistance, easy to get a high degree of smoothness and gloss after the coated paper after calendering, but poor water retention styrene-butadiene latex, pH values ??below a precipitate 6:00 shortcomings without used alone. Although the bond strength is low starch flat carbon paper, but because it does not form a film, and better water retention and is widely used. NCR adhesive coating usually consists of three kinds of adhesives (PVA, styrene-butadiene latex, modified starch) with the use of both high strength makes the adhesive system also contains an open surface state, to minimize gum Effect of viscosity on the film-forming agent is a color effect, while the presence of the starch during drying helps to maintain the water content of the coating.
