Abstract
A tamper-evident adhesive label stock (10) comprising a first layer (1), a second layer (2) and a release liner (3), wherein the second layer (2) is positioned between the first layer (1) and the release liner (3) and contains an irreversible photochromic substance that undergoes a color change upon exposure to a UV-light source and wherein the first layer (1) is UV-light blocking such that the irreversible photochromic substance in the second layer (2) is not activated as long as it it covered by the first layer (1), and wherein the first and second layers are bonded to each other and wherein the label stock (10) further comprises either in the second layer or in an additional bottom layer (6) positioned between second layer (2) and release liner (3) an adhesive material (7) by which the label (10) can be adhered to a substrate (8) and wherein photochromic substance is activated by UV-light to undergo a color change that is visible to the naked eye and that is irreversible. Further provided is the label stock applied as label to a substrate, and a method of preparing the label stock.
