continuous copy paper carbonless copy paper

Carbonless copy paper (CCP), non-carbon copy paper, or NCR paper is a type of coated paper designed to transfer information written on the front onto sheets beneath. It was developed as an alternative to carbon paper and is sometimes misidentified as such. Carbonless copying can be used to create multiple copies; this may be referred to as multipart stationery.

HOW CARBONLESS PAPER WORKS?
With carbonless paper, the copy is produced by a chemical reaction between two different coatings, which are generally applied to the front and back of a base paper. This color reaction is caused by pressure (typewriter, dot-matrix printer, or writing instrument).

The first and uppermost layer (CB = Coated Back) consists of microcapsules containing a colorless but color-producing substance. When mechanical pressure is exerted on these capsules, they burst and release the color-producing substance, which is then absorbed by the second layer (CF = Coated Front). This CF layer consists of a reactive substance which combines with the color-releasing substance to produce the copy.

In the case of form sets with more than two sheets, another type of sheet is required as a central page which receives the copy and also passes it on (CFB = Coated Front and Back).
