FIELD: printing.
SUBSTANCE: invention relates to a security element, in particular to security labels or adhesive tapes. The security element comprises the following layers: a) a substrate-carrier; b) a reflecting layer or layer with a high refractive index; c) a partial separation layer of varnish; d) the adhesive intermediate coating applied to the entire surface; e) the adhesive layer applied on the entire surface where the adhesive coating d) is in those places where there is no separation layer of varnish c), adhesion of the layer b) with the substrate-carrier a) is disturbed, and in case of attempt to manipulate due to separation of the layer b) it is separated from the substrate-carrier a) in those areas where there is no separation layer of varnish c).
EFFECT: proposed security element provides ease of detection of manipulation with it.
