摘要:
The invention relates to a security foil consisting of two or more carrier substrates which have at least one optically active structure and at least two metal layers, wherein the security foil is composed as follows: a) a first carrier substrate, b) a first radiation-curable paint layer into which an optically active structure is incorporated, c) a first metal layer, d) a protective paint layer, e) an adhesive layer, f) a second carrier substrate, g) a second radiation-curable paint layer, h) a second metal layer, i) optionally a protective paint layer, and k) optionally an adhesive coating, and wherein the adhesion between the layers g) and h) or f) and g) is significantly lower than the adhesion between the remaining layers.
摘要:
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.

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