Abstract

A transparent, tamperproof seal which is utilized for the protection of signed texts and documents. The tamperproof transparent seal for signed texts or documents, inclusive of checks, is constituted of at least one card having on one side thereof, an adhesive inking and varnishing multilayer lamina which is at least partially transparent, and with a suitable movable sheet-like carrier or substrate consisting of a transparent plastic material; and on the other side, possessing a delayed-action adhesive selected from a group of pressure-sensitive adhesives, and which is protected by a liner, heat-activated adhesives and wet-activated adhesives. The lamina is intended to be applied onto the text with the subsequent removal of the carrier; with an identical number with prefix, set in a position chosen being present within and outside the confines of the seal, the lamina bearing a number with a prefix, providing an attestation, and an adjacent background covering stripe, upon which number and stripe there is to be superimposed the signature, the number of the seal being shown by means of a non-impact printing device in a preestablished sequence so as to be individualized and clearly evident, while the prefix, which is generally alphabetical, is obtained by an ink transference upon detaching the carrier.
