Abstract (en)
A release liner (10) comprises a substrate (12) and a coating (14) on the substrate (12) that provides release properties against a pressure sensitive adhesive. The substrate (12) is sensitive to irradiation, under which it can change its local optical properties, thus being provided with a visible information which cannot be erased or altered without destroying the substrate (12). <IMAGE>
