Abstract
The present invention is a tamper proof label comprised of a thicker support portion and a thinner fragile portion. The label is formed of a plurality of layers of varnish, adhesive, plastic, and ink. The label incorporates an authentication region in which the text can be readily deciphered only with a special viewer. The top surface of the label can be written on with ink and is difficult to erase without destroying the fragile portion of the label. The label is adhered to a product by an adhesive which becomes aggressively bonded to the product over a relatively short period of time. In addition, the adhesive leaves a residue which is visible when illuminated with ultraviolet light.
