Abstract:
A single sheet of paper having two surfaces and capable of reproducing information entered on both of its two surfaces, comprising:a single sheet of paper having two surfaces, one of which is a front surface, an other of which is a back surface, a first portion of the single sheet of paper being an original panel having a front surface which is the front surface of the single sheet of paper and having a back surface which is the back surface of the single sheet of paper, a second portion of the single sheet of paper being a copy panel having a front surface which is the front surface of the single sheet of paper and having a back surface which is the back surface of the single sheet of paper;a first carbonless coating applied only to the original panel, on the front and back surfaces thereof;a second carbonless coating applied only to the copy panel, on the front and back surfaces thereof; andthe first and second carbonless coatings being selected from a common carbonless system wherein the second carbonless coating is capable of revealing an image when the first carbonless coating is pressed against the second carbonless coating;wherein:when the single sheet of paper is folded in a first direction, so that the original panel is disposed over the copy panel and the front surface of the original panel is exposed for entering first information thereon, the first information entered on the front surface of the original panel causes the first carbonless coating on the back surface of the original panel to press against the second carbonless coating on the back surface of the copy panel, thereby resulting in the second coating on the back surface of the copy panel revealing an image of the first information entered on the front surface of the original panel; andwhen the single sheet of paper is folded in a second direction, so that the original panel is disposed over the copy panel and the back surface of the original panel is exposed for entering second information thereon, the second information entered on the back surface of the original panel causes the first carbonless coating on the front surface of the original panel to press against the second carbonless coating on the front surface of the copy panel, thereby resulting in the second coating on the front surface of the copy panel revealing an image of the second information entered on the back surface of the original panel.
