The invention relates to a security label or adhesive tape with evidence of tampering, having a flexible carrier substrate 1 on the basis of a flexible plastics film, and characterised in that the following layers are applied to a surface of the carrier substrate: a) an embossed lacquer layer 2; b) a semi-transparent metal layer or a layer with a high refractive index 3; c) a partial separating lacquer layer 4 in the form of letters, signs, symbols, lines, guilloche, numbers or writing; d) one or more lacquer layer(s) 5 with optical properties; and e) a self-adhesive coating 6. In the regions not coated with the separating lacquer layer 4, the adhesion of layer 3 to layer 5 and the adhesion of layer 6 to the object to be secured is greater than the adhesion of layer 5 to layer 6, or the adhesion of layer 3 to layer 5 and the adhesion of layer 5 to layer 6 is greater than the adhesion of layer 6 to the object to be secured, and in the regions that are coated with the separating lacquer layer 4, the adhesion of layer 5 to layer 6 and the adhesion of layer 4 to layer 5 is greater than the adhesion of layer 3 to layer 4, or the adhesion of layer 3 to layer 4 and the adhesion of layer 5 to layer 6 is greater than the adhesion of layer 4 to layer 5. |
