ABSTRACT:
Carbon paper duplicating sheets, such as those used in credit-card transaction forms, are made easily destroyable after authorized use without hand-soiling by incorporating, into the tissue paper base of the carbon paper sheets, filament strands arranged in repetitively alternating angular relationship to the edges of, and throughout, the carbon paper sheets. Duplicating-ink-free areas are provided at opposite edges of each sheet so that it may be grasped between the thumb and fingers of each hand to render the used carbon paper shredded, uncopyable and therefore safely disposable. The addition of perforations in the paper base in selected areas may be made to enhance the easy destructibility of the duplicating sheets.
