A tamper-evident adhesive security tape or label includes a flexible backing substrate with a surface that bears an embossed varnish layer, a semitransparent metal layer and/or a high refractive index layer, a partial release varnish layer, one or more varnish layers having optical properties, a full-area release varnish layer, a full-area varnish layer, and a self-adhesive coating layer. In regions not coated with the partial release varnish layer, an adhesion of the embossed varnish layer, the semitransparent metal layer and/or the HRI layer, the one or more varnish layers having optical properties, the full-area release varnish layer, the full-area varnish layer, the self-adhesive coating layer, and an article to be secured to one another is greater than an adhesion of the one or more varnish layers having optical properties to the full-area release varnish layer or an adhesion of the full-area release varnish layer to the full-area varnish layer.

1. A tamper-evident adhesive security tape or label comprising: a flexible backing substrate based on a flexible polymeric film, wherein one surface of the flexible backing substrate bears the following applied layers:a) an embossed varnish layer,b) a semitransparent metal layer and/or a high refractive index layer,c) a partial release varnish layer in a form of letters, signs, symbols, lines, guilloches, numbers or writing,d) one or more varnish layers having optical properties,e) a full-area release varnish layer,f) a full-area varnish layer, andg) a self-adhesive coating layer, wherein, in regions that are not coated with the partial release varnish layer: an adhesion of the embossed varnish layer, the semitransparent metal layer and/or the high refractive index layer, the one or more varnish layers having optical properties, the full-area release varnish layer, the full-area varnish layer, the self-adhesive coating layer, and an article to be secured to one another is greater than an adhesion of the one or more varnish layers having optical properties to the full-area release varnish layer, or the adhesion of the embossed varnish layer, the semitransparent metal layer and/or the high refractive index layer, the one or more varnish layers having optical properties, the full-area release varnish layer, the full-area varnish layer, the self-adhesive coating layer, and the article to be secured to one another is greater than an adhesion of the full-area release varnish layer to the full-area varnish layer;andwherein, in regions that are coated with the partial release varnish layer: an adhesion of the embossed varnish layer, the semitransparent metal layer and/or the high refractive index layer, the partial release varnish layer, the one or more varnish layers having optical properties, the full-area release varnish layer, the full-area varnish layer, the self-adhesive coating layer, and the article to be secured to one another is greater than an adhesion of the semitransparent metal layer and/or the high refractive index layer to the partial release varnish layer, or the adhesion of the embossed varnish layer, the semitransparent metal layer and/or the high refractive index layer, the partial release varnish layer, the one or more varnish layers having optical properties, the full-area release varnish layer, the full-area varnish layer, the self-adhesive coating layer, and the article to be secured to one another is greater than an adhesion of the partial release varnish layer to the one or more varnish layers having optical properties; andthe adhesion of the semitransparent metal layer and/or the high refractive index layer to the partial release varnish layer is lower than the adhesion of the one or more varnish layers having optical properties to the full-area release varnish layer and the adhesion of the full-area release varnish layer to the full-area varnish layer, or the adhesion of the partial release varnish layer to the one or more varnish layers having optical properties is lower than the adhesion of the one or more varnish layers having optical properties to the full-area release varnish layer and the adhesion of the full-area release varnish layer to the full-area varnish layer. 2. The tamper-evident adhesive security tape or label of claim 1, wherein the flexible backing substrate consists of a transparent polymeric film. 3. The tamper-evident adhesive security tape or label of claim 1, wherein the one surface of the flexible backing substrate is a first surface, and a second surface of the flexible backing substrate bears a print primer layer. 4. The tamper-evident adhesive security tape or label of claim 3, wherein the tamper-evident adhesive security tape or label has printing on the print primer layer. 5. The tamper-evident adhesive security tape or label of claim 1, wherein the one surface of the flexible backing substrate is a first surface, and a second surface of the flexible backing substrate bears a release varnish layer. 6. The tamper-evident adhesive security tape or label of claim 1, wherein an adhesion promoter layer is disposed situated between the flexible backing substrate and the embossed varnish layer. 7. The tamper-evident adhesive security tape or label of claim 1, wherein a release layer is disposed between the flexible backing substrate and the embossed varnish layer. 8. The tamper-evident adhesive security tape or label of claim 1, wherein the one or more varnish layers having optical properties is formed by multicolor printing, as a color gradation layer and/or as a layer comprising effect pigments and/or security dyes or pigments. 9. The tamper-evident adhesive security tape or label of claim 1, wherein the letters, signs, symbols, lines, guilloches, numbers or writing become recognizable and are positive on the article to be secured and negative on the removed backing substrate, or vice-versa after triggering of a tamper evidence feature. 10. The tamper-evident adhesive security tape or label of claim 1, wherein the semitransparent metal layer and/or the high refractive index layer is a semitransparent metal layer comprising Al, Cu, Fe, Ag, Au, Cl, Ni, Zn, Sn, Pt, Ti, Pd, or an alloy of these metals. 11. The tamper-evident adhesive security tape or label of claim 1, wherein the semitransparent metal layer and/or the high refractive index layer is an HRI layer comprising a metal compound. 12. The tamper-evident adhesive security tape or label of claim 1, wherein the semitransparent metal layer and/or the high refractive index layer is an HRI varnish layer. 13. The tamper-evident adhesive security tape or label of claim 1, wherein the embossed varnish layer is an embossed UV varnish layer. 14. The tamper-evident adhesive security tape or label of claim 1, wherein the embossed varnish layer is a hot-stamping varnish layer. 15. The tamper-evident adhesive security tape or label of claim 1, wherein the partial release varnish layer and the full-area release varnish layer consist of the same components in different proportions. 16.
