PälBchungBSafe adhesive label and process for its manufacture

The invention relates to a counterfeit-proof adhesive label and a method of making this counterfeit-proof adhesive label that can be easily moved without destroying it difficult to remove or change.

In certain applications it is highly desirable that the adhesive labels used are forgery-proof. For example, it is desirable to transmit vehicle inspection signs from one vehicle to the other. Or it may be desirable Forgery attempts on information contained on a sign, e.g. a price indication.

Adhesive signs are often locally separated from the production of the basic material from which the signs are cut out are produced. It is therefore common for a sign manufacturer to keep his basic stock of Obtains this material from a manufacturer, prints the desired information on this material and then the

Cut out pupils from this material. Usually the signs are printed first and then cut out. Sometimes, on the other hand, the pupils also become after the Cut out printed.

The object of the invention is to create two unequal halftone products of the base material, which can be seen as end-products after one of the semi-finished products can be combined to form a tamper-proof adhesive label material has been printed by the manufacturer of the adhesive label ;. The end product can then be cut into individual adhesive labels or using another method Process individual adhesive labels. An essential novelty of the invention is that the production of the green material for the counterfeit-proof adhesive labels at different locations and before the production of the counterfeit-proof ones Adhesive signs can be executed. Furthermore, the production of the adhesive labels according to the invention with the help of the printing equipment customary in sign production and cutting or perforating dies and a simple coating process can be performed each Sign maker typically involved in other sign manufacturing processes uses, e.g. if he uses a sign sheet with a clear plastic layer that has an adhesive layer made of a transparent adhesive that sets under pressure. Thus, according to the invention created an improved, forgery-proof adhesive label construction.

The invention is described in detail below with reference to an embodiment shown in the drawings. It shows:

1 shows a schematic cross section of an embodiment an adhesive label according to the invention which is attached to a transparent carrier layer, e.g. an automobile windshield has been applied;

2 shows a schematic cross section of the adhesive label according to FIG. 1 before application to the carrier layer;

3 and 4 are schematic cross-sections of the semi-finished products the adhesive label material from which the adhesive labels according to FIGS. 1 and 2 are manufactured.

Since the complete adhesive label according to FIG. 2 is a composite structure 3 and 4, the latter will be described first. That Semi-finished product according to FIG. 3 consists of a first end product layer 1 made of a transparent adhesive, a second end product layer 2 made of a printable transparent film and a protective layer 11 which is arranged below the first layer 1 in order to protect the adhesive. The glue of the first layer 1 can be an adhesive that sets under pressure. Although it is intended, the protective layer 11 on the adhesive label to leave the shield applied to a backing layer, the protective layer 11 is not a part of the glued-on sign and is therefore not used as a final product layer considered.

The second layer 2 should not be self-supporting. However, it could initially be made self-supporting will. E.g. it can be used in a sufficiently small

ke, e.g. 1 mm, can be poured onto the adhesive layer 1, so that the special film material used, e.g. styrene, nitrocellulose, acetate or vinyl, is self-supporting Film forms. The non-self-supporting property of the layer 2 can thereafter, as described later will be produced by its cutting or perforating operation.

The semi-finished product according to FIG. 4 consists of one third end product layer 3 made of an adhesive, a fourth end product layer 4 made of a cover sheet made of paper or plastic and a protective layer 12 to protect the final product layer 3, which consists of a pressure-setting Adhesive can exist. The cover sheet 4 can be transparent or opaque. The protective layer 12 is not an end product layer; it is made before the two ready-to-veal products are combined according to FIGS. 3 and 4 removed.

During the production of the actual adhesive labels, the label content is mirror-inverted on a surface 14 the layer 2 of the halved product according to FIG. 3 is printed. This content can have a purely decorative character or / and consist of printed characters, e.g. a price indication or the like. exist. After printing, as already mentioned, the cutting or perforating operation can be carried out in order to generate or reinforce the non-self-supporting property of the layer 2. At this Operation, the layer 2 is incised or perforated so that die cuts 15 are created that calibrate extend partially or, as shown, entirely through the thickness of the layer 2, and which also extend entirely or partially can extend through the adhesive layer 1. The adhesive layer 1 has the property to close again automatically. However, it should be avoided that the

Layer 2 is made up of layers 1 and 1. worn, into which the die cuts 15 do not penetrate so deep that they rob the semi-finished product according to FIG. 5 of its self-supporting property when the protective layer 11 has not yet been removed.

After the protective layer 12 has been removed, is the semi-finished product according to FIG. 4 with the semi-finished product 3 combined in such a way that the third end product layer 3 over the printed surface 14 of the second end product layer. This layering of the two semi-finished products according to Fig. 4 and 3, the product is found according to FIG. 2. The manufacturer of the adhesive labels can now either use this Stage or later the printed and combined shield material by cutting or the like. disassemble into individual signs. Alternatively, the semi-finished products can be used accordingly. 3 and 4 are cut to the desired shape before printing and joining them; this procedure is however, the handling of the workpieces is very cumbersome.

The relative cohesion / adhesion properties between the adhesive layers 1 and 3 and the surrounding final product layers (layers 20 and 2 surround adhesive layer 1 and layers 2 and 4 surround adhesive layer 3) and the carrier layer are selected so that the Layer 4 is easier to separate from layer 2 than layer? of the material, for example Gla.s, the carrier layer <Ό to which the adhesive plate is applied.

achild positioned on the transparent carrier layer 20, on which it is to be attached, e.g. a motor vehicle windshield .

The printed characters of the surface 14 are then visible through the layers 20, 1 and 2. Any attempt to change or remove the label will result in progressive destruction of layer 2, which clearly shows that an attempt to forge the label has been made. Since the layer 2 is not self-supporting and since the layer 4 is more easily separated from the layer 2 than the layer 2 can be separated from the carrier layer 20, it is obvious that it is very difficult not to destroy the sign when attempting to close the sign remove oner to change.

The second end product layer 2 made of a printable transparent film can easily be immersed in water or another common household solvents. The adhesive layer 3 can be or be water-soluble can be an additional water-soluble layer between the printable transparent film 2 and the cover layer 4 to be ordered. The cover layer 4 can consist of a paper having a low internal strength. All these properties increase the difficulty of destruction of the shield when trying to change the shield.

The invention consists essentially in a forgery-proof Adhesive label, which is attached through a transparent carrier layer, e.g. a motor vehicle windshield, is visible, and which is made as a composite construction of two flexible sheets after one of the sheets was printed mirror-inverted.
