- the invention relates to a double-sided pressure-sensitive adhesive tape with differently adhesive sides, optionally in the form of die-cuts or cut molded parts, for the bonding and residue-free and damage-free redetachment of flexible storage media such as, for example, of the CD, CD-ROM or DVD type plan and in particular also on curved, curved or kinked surfaces, essentially without detaching the flexible storage media, in particular in the edge or edge area, during the bonding period, the side to which the flexible storage media are glued essentially on human skin is not liable or does not feel sticky.
- flexible storage media such as, for example, of the CD, CD-ROM or DVD type plan and in particular also on curved, curved or kinked surfaces, essentially without detaching the flexible storage media, in particular in the edge or edge area, during the bonding period, the side to which the flexible storage media are glued essentially on human skin is not liable or does not feel sticky.
- Flexible or flexible optical storage media such as the CD or CD-ROM type are known for example from WO 01/52252 A1.
- the product structure of such storage media consists of a plastic film, typically from the group of polyesters or polycarbonates, a sol-gel layer applied thereon or alternatively a layer of a photopolymer, optionally a further metallization layer and an optional additional protective lacquer layer.
- the information is not read out through the plastic film, but from the opposite Side, either the open, optionally metallized sol-gel layer, alternatively the photopolymer, or optionally through the protective lacquer layer. Accordingly, this page, hereinafter referred to as the readout page, must be particularly protected against mechanical or other damage.
- Such storage media thanks to their flexibility or flexibility, can adapt to the surfaces of many everyday objects or to their packaging, such as cans, beverage cans, bottles, pouches, bags, boxes, cartons or boxes, etc., which in principle opens up the possibility of them for example as an information and advertising medium to save space and to be transported to the target persons with little effort.
- Double-sided adhesive articles the sides of which stick to different degrees, are also known, for example from DE 43 16 317 A1.
- a variety of known systems can be used as the pressure sensitive adhesive for the side of the adhesive article on which the readout side of the flexible storage medium is to be glued, but these are all without exception weaknesses.
- Pressure-sensitive adhesives based on natural rubber can be adjusted so that they initially have a suitable adhesive strength and are easily removable at the beginning. However, these pressure sensitive adhesives are not stable to aging. This can happen after a short while extremely greasy or lacquer-like hardened residues on the storage media.
- Pressure sensitive adhesives based on polyacrylate are considerably more stable to aging, but as a rule they attract strongly to the surfaces of the storage media.
- the term “mounting” is understood by the person skilled in the art to mean an increase in the bond strength when the adhesive bond is stored. These pressure-sensitive adhesives are therefore difficult to remove and, moreover, usually leave residues on the surfaces.
- Edge area often leads to unintentional detachment of the storage media from the pressure sensitive adhesive.
- both crosslinked and uncrosslinked polyacrylate pressure sensitive adhesives often lead to irreversible, visually recognizable changes on the surface of the readout side of the storage medium, so-called deformations. Imprints of the adhesive tape in the area of the edges and a matting of the surface of the
- there must be no unintentional detachments in the edge or edge area of the bonds during the duration of the bond because then the read-out side of the storage medium would no longer be adequately protected from damage by external influences at the relevant points.
- the adhesive tape should not feel sticky after the storage medium has been detached, because this would impair the quality of the product to which the adhesive tape was adhered.
- a double-sided adhesive tape optionally in the form of die-cuts or cut molded parts, as set out in the main claim.
- the subclaims relate to advantageous developments of the adhesive tape and possible uses.
- the invention relates to a double-sided pressure-sensitive adhesive tape with differently adhesive sides, containing at least one adhesive layer, wherein

- the adhesive layer can be applied from solution or solvent-free by means of the extrusion or coextrusion process, depending on the embodiment, on an anti-adhesive, sheet-like material or on the backing material of a multi-layer adhesive tape.
- double-sided adhesive tapes according to the invention consist of three or more layers, namely a carrier layer, which in turn can be a laminate of several individual layers, a known pressure-sensitive adhesive layer, which is not restricted with regard to the polymer base, and a pressure-sensitive adhesive layer according to the invention applied to the opposite side of the carrier Ethylene vinyl acetate copolymer, the last-mentioned layer in any case has a lower adhesive strength than the first-mentioned.
- adhesive tapes according to the invention consist of the two different pressure-sensitive adhesive layers, the two layers being direct on top of each other
- One such strapless two-layer laminate falls under the heading of the so-called transfer transfers, is made by applying the adhesive layers to an anti-adhesive, sheet-like material and is also presented in this form or optionally in cutting or Stamping processes processed.
- At least the weaker adhesive side is formed from the EVA-based pressure sensitive adhesive.
- Typical total product thicknesses are 20 ⁇ m to 300 ⁇ m, preferably 30 ⁇ m to 200 ⁇ m, particularly preferably 40 ⁇ m to 100 ⁇ m, without wishing to restrict the invention with these details.

- Metal foils, fabrics, nonwovens, creped or uncreped papers as well as laminates from the individual layers and foils can also be used as backing layers.
- the total thickness of the carrier layers used is typically between 10 and 100 ⁇ m, without wishing to restrict the invention with this information.
- the well-known pressure-sensitive adhesive layer for the more adhesive side of the adhesive tape has the task of adhering so well to surfaces of common everyday objects or to their packaging, such as cans, beverage cans, bottles, bags, bags, boxes, boxes or boxes, etc. that there is no or at least no premature, unwanted detachment of the adhesive tape from the everyday objects or their packaging.
- Such a task is accomplished by a large number of known pressure sensitive adhesives or types of pressure sensitive adhesives of different polymer bases.

Essentially all pressure-sensitive adhesives come into question whose adhesive strength, measured based on steel (see test methods), is greater than approximately 1.0 N / cm, preferably greater than 2.0 N / cm, particularly preferably greater than 3.0 N / cm. In any case, the adhesive strength of the known pressure-sensitive adhesive, which is intended to adhere to the surfaces of conventional consumer articles or their packaging, is higher than that of the ethylene-vinyl acetate copolymer-based pressure-sensitive adhesive to which the read-out side of the storage medium is to adhere. The self-adhesive based on ethylene vinyl acetate copolymer intended for the weaker adhesive side of the adhesive tape is said to be light, non-destructive and residue-free

- the adhesive strength of the ethylene vinyl acetate copolymer-based pressure sensitive adhesive for the weaker adhesive side of the adhesive tape is typically between approximately 0.01 and 0.4 N / cm, measured on steel (see test methods), or between approximately 0.1 and 0.8 N / cm, preferably between 0.2 and 0.6 N / cm, measured on the read-out side of the storage medium (see test methods).
- Adhesive tapes according to the invention have adhesive strengths on steel with the more adhesive side (see test methods), determined at a peel angle of 180 ° of greater than approximately 1.0 N / cm, preferably greater than 2.0 N / cm, particularly preferably greater than 3.0 N / cm on.
- the more adhesive side adheres so well to the surfaces of common everyday objects or to their packaging, such as cans, beverage cans, bottles, bags, bags, boxes, cartons or boxes, etc., that during normal use there is no or at least no premature , unwanted detachment of the adhesive tape from the everyday objects or their packaging takes place.
