The invention relates to a tamper-evident adhesive security tape or label comprising a flexible backing substrate based on a flexible polymeric film, which is characterized in that one surface of the backing substrate bears the following applied layers: 11. A tamper-evident adhesive security tape or label comprising a flexible backing substrate based on a flexible polymeric film , characterized in that one surface of the backing substrate bears the following applied layers:{'b': '2', 'a) an embossed varnish layer ,'}{'b': '3', 'b) a semitransparent metal layer and/or a high refractive index layer ,'}{'b': '4', 'c) a first, partial release varnish layer in the form of letters, signs, symbols, lines, guilloches, numbers or writing ,'}{'b': '5', 'd) one or more varnish layers having optical properties ,'}{'b': '6', 'e) a second, full-area release varnish layer ,'}{'b': '7', 'f) a further full-area varnish layer ,'}{'b': '8', 'g) a self-adhesive coating ,'}{'b': 4', '8', '9', '5', '6', '6', '7, 'where, in the regions not coated with the release varnish layer , the adhesion of all the layers to one another and the adhesion of the layer to the article to be secured are greater than the adhesion of the layer to the layer or of the layer to the layer , and where,'}{'b': '4', 'in the regions coated with the release varnish layer ,'}{'b': 8', '9', '3', '4', '4', '5, 'the adhesion of all layers to one another and the adhesion of the layer to the article to be secured are greater than the adhesion of the layer to the layer or of the layer to the layer ,'}and where in particular{'b': 3', '4', '4', '5', '5', '6', '6', '7, 'the adhesion of the layer to the layer or of the layer to the layer is lower than the adhesion both of the layer to the layer and of the layer to the layer .'}21. The adhesive security tape or label of claim 1 , characterized in that the backing substrate consists of a transparent polymeric film.318. The adhesive security tape or label of claim 1 , ...
