Claim:
Self-adhesive security label for a data carrier exemplified by a security document or a document of value, comprising a substrate on the front side of which are applied security features and on the back side of which is provided a cold adhesive layer, wherein the security label includes an integrated circuit disposed in a recess of the adhesive layer adapted to store security data, the recess with the integrated circuit being closed by a self-adhesive covering element, and an antenna disposed between the substrate and the adhesive layer, said antenna connected with the integrated circuit so as to provide a contactless communication with the integrated circuit wherein the front-side security features contain a printed area produced by an intaglio printing method and, wherein the adhesive strengths of the self adhesive covering element and of the bond between the integrated circuit and the antenna are adjusted relative to each other such that a removal of the security label from the data carrier results in damaging the antenna or separating the antenna from the integrated circuit.
