Carbonless Copy Paper

Carbonless copy paper (CCP), non-carbon copy paper, or NCR paper is an alternative to carbon paper, used to make a copy of an original, handwritten (or mechanically typed) document without the use of any electronics. The process was invented by chemists Lowell Schleicher and Barry Green, working for the NCR Corporation, as a biodegradable, stain-free alternative to carbon paper. Early product literature piggybacked on NCR's corporate name by calling the paper No Carbon Required paper, a simple bacronym alternative to National Cash Register.
