<p>The invention relates to a label with improved antiforgery security, comprising an adhesive layer applied to the lower face of the support layer. The invention in is characterized in that in or on the bare face of the adhesive layer a plurality of discrete inclusions are present which contain at least one reversibly detective additive. When the label is bonded to a base, the discrete inclusions are forced into the adhesive mass to such a degree that the layers of the label present above the inclusions are deformed, thereby forming haptically distinguishable and optically visible bumps in the surface of the upper support layer.</p> |
