Carbonless Paper Technical Data
Coated Paper Description and Construction
Carbonless paper consists of a top sheet, a bottom sheet, and possibly one or several intermediate sheets. The top sheet (CB) has a curl coat on the front side and a coating consisting of binder and microcapsules containing fill and colour formers on the reverse side. The bottom sheet (CF) features a coating of binder and developer on the front side and a release coating on the reverse side. The intermediate sheets (CFB) contain the CF front side coating on the front and the CB reverse side coating on the back.
The microcapsules are designed to rupture at a pressure of about 90,000 Pa (>1,270 psig) and will release their fill consisting of colourformers and transfer agents to the developer sheet.
