Abstract

Improvements in tamper-resisting multipart negotiable instruments, such as airline ticket books are disclosed. The books include at least two webs. The first web includes, on its second surface, a medium for transferring an image to the first surface of a second web in contact therewith when a corresponding image is inscribed on the first surface of that web. The first surface of the second web is in contact with the second surface of the first web and includes an image receiving layer capable of receiving an image transferred from the second surface of the first web. The image receiving layer includes a particulate mixture erasably bonded to the second web, which becomes defaced when rubbed with an organic solvent, and which is removable when an adhesive tape is applied to the image receiving layer and is pulled away therefrom.
