The present invention relates to a sticker for sticking onto an object, having an upper side (Ia) and an underside (Ib), having a substrate (2) which is provided on the upper side (Ia) and has a region (3) for storing an optical structure, having a contact surface (4, 11) which is provided on the underside (Ib), and having an adhesive (5, 6, 12, 14) which is connected to the contact surface (4, 11) for sticking the sticker (A1, A2, A3, A4, A5, A6) onto the object. The problem of specifying a sticker for sticking onto an object, which sticker ensures satisfactory quality of the reproduction of the information contained in the optical structure even in the case of unevennesses of the surface to be adhesively bonded, is solved by at least one part region of the substrate (2) being decoupled from the object in force terms in the adhesively bonded state.

In a method of entering information into an optically writable and readable data storage medium having a polymer film which can be changed locally by heating in order to store information and to which there is assigned an absorber dye (34) which is set up to absorb a write beam (36), at least partly, and to transfer the heat produced in the process, at least partly, locally to the polymer film, first of all the absorber dye is heated locally in a predetermined region of the polymer film in accordance with the information to be entered, specifically by means of a pulsed write beam (36). After that, the absorption properties of the absorber dye (34) are changed by means of light, to be specific preferably by means of a fixing beam (37) which bleaches (38) the absorber dye (34) in the written region of the polymer film.

The invention relates to a label to be used as a security feature with a substrate layer and with an optically changeable section which can be microstructured, wherein the optically changeable section is connected to the substrate layer. Thus, the technical problem of creating a label of the type previously mentioned which is simple, reliable, and tamper-proof is solved. The substrate layer of said label is provided with at least one recess which is arranged along a line which runs slightly below the optically changeable section. The invention also relates to a packaging, in which at least one label with a container is connected to a closure having at least one recess arranged in the area between the container and the closure.
