Pressure-sensitive adhesive (PSA) strips, configured or adapted for the residue-free and non-destructive removal by which by substantially expanding it in the plane of adhesion, are provided. The PSA strips comprise at least one adhesive compound layer consisting of a PSA compound, constituted by vinyl aromatic block copolymers and one or more adhesive resins, at least 75 wt.-% (relative to the total amount of resin) of a resin being selected that has a DACP (diacetone alcohol cloud point) of greater than &#x2212;20&#xb0; C., and a softening point (ring & ball) of greater than or equal to 70&#xb0; C., and the PSA compound has being foamed.

Removable pressure-sensitive adhesive strip

The invention relates to a pressure-sensitive adhesive strip composed of at least three layers, comprising

Pressure-sensitive adhesive strip

The invention relates to a pressure-sensitive adhesive strip, for the residue-free and nondestructive removal by which by substantially expanding it in the plane of adhesion, comprising an adhesive compound layer, said adhesive compound layer consisting of a pressure-sensitive adhesive compound, constituted by vinyl aromatic block copolymers and adhesive resins, at least 75 wt.-% (relative to the total amount of resin) of a resin being selected that has a DACP (diacetone alcohol cloud point) of greater than &#x2212;20&#xb0; C., preferably greater than 0&#xb0; C., and a softening point (ring & ball) of greater than or equal to 70&#xb0; C., preferably greater than or equal to 100&#xb0; C., and the pressure-sensitive adhesive compound being foamed.

In an example holographic data storage medium, which has a polymer film which serves as a storage layer and can be changed locally by heating, the polymer film is set up as a top layer of the data storage medium. Arranged underneath the polymer film is an absorber layer which has an absorber dye. The absorber dye is set up to at least partly absorb a write beam serving to put information in and to discharge the heat produced in the process at least partly locally to the polymer film. In an advantageous refinement of the example data storage medium, there is an adhesive layer underneath the absorber layer and a partly transparent reflective layer between the polymer film and the absorber layer.

Holographic data-storage medium

The invention relates to a method of providing an article with identifying information, in which a hologram is provided from which at least first and second hologram patterns separated physically from each other can be reproduced. In this case, provision is made for the hologram to be produced in such a way that the first and second hologram patterns can generally be reproduced in one and the same direction but in different planes.
