AA Grade NCR Carbonless Printing Paper for Bank Payment Receipt

Carbonless papers are bond-stock sheets treated with microencapsulated dye plus reactive resins and clays. They come in four main types—Coated Back (CB), Coated Front and Back (CFB), Coated Front (CF), and Self‑Contained (SC)—each serving a specific role in multi‑part forms.

CB – Coated Back
Beginning as ordinary bond paper, CB sheets have tiny dye capsules on their reverse surface. When pressure (like writing) breaks these capsules, the released dye transfers to clay‑and‑resin coatings on a CF sheet below, creating a duplicate of the original mark.

CFB – Coated Front and Back
Also based on bond paper, CFB stock features a clay‑resin layer up front and microencapsulated dye on the back. In sets exceeding two sheets, these middle pages both receive impressions from the CB above and pass copies down to the CF beneath.

CF – Coated Front
CF paper is bond stock with only a clay‑and‑resin coating on its face. It reacts to dye from a CB or CFB sheet above, producing the last copy in a multipart assembly.
