ABSTRACT

Carbonless paper is a paper stock that is coated with a pressure-activated inking system used as a method of recording an entry on multiple copies of a document at one time. The basis for the carbonless paper systems is microencapsulation of dye components. The process of microencapsulation was invented by Barry Green in 1950. Green, a research scientist for National Cash Register (NCR) of Dayton, OH, worked closely with fellow NCR scientist Lowell Schleicher to turn his concept into the basis of the systems of carbonless paper still in use to this date. The patent for their microencapsulation system was filed on June 30, 1953, and the first commercial sale of their new product was made on March 26, 1954. The term NCR Paper is commonly used to describe carbonless paper, but NCR Paper is actually a brand name.
