<p>This tamper-proof adhesive plaque or label is suitable for application e.g. to documents or vehicles. It has a substrate which carries elements of information and a transparent layer of plastic, which is intended never to become completely hard. At the edges of the plaque, there are novel projections, e.g. points (9), of an even- or uneven distribution. The surface of the plaque is coated, at least partially, with an adhesive material.</p> |
