    Abstract: Laminates designed and equipped to be separated after long-term bonding are provided. The laminates comprise a first pressure sensitive adhesive layer, a separation layer, and a second pressure sensitive adhesive layer. The separation layer comprises a laser-sensitive pigment which at the same time is coloring, and so preferably a black coloration is produced, and consists of a cured coating material, preferably an electron beam-cured or UV-cured coating material, which is at least partly removable by laser irradiation, wherein the first pressure sensitive adhesive layer and/or the second pressure sensitive adhesive layer are laser beam-translucent.

    Abstract: The present invention relates to a film laminate which is formed and designed to be separated after permanent adhesive bonding, comprising the following layers: a) a first adhesive compound layer, preferably a contact adhesive layer, b) a first support material, preferably in the form of a film, c) a separating layer, d) optionally a second support material, preferably in the form of a film, e) a second adhesive compound layer, preferably a contact adhesive layer, characterised in that the separating layer—has a thickness of 40 nm to 500 nm,—is black,—has a maximum transmittance of 30%,—consists of a metal which can be at least partially removed by laser radiation, the second adhesive compound layer being translucent to laser beams and/or the first adhesive compound layer and the first support material being translucent to laser beams.

    Abstract: Provided are methods for adhesively bonding profiles to substrate surface. An example method includes plasma-treating each of a profile surface and a first adhesive side of a layer of pressure sensitive adhesive. The pressure sensitive adhesive includes a) 40 to 70 wt %, based on the total weight of the pressure sensitive adhesive, of at least one poly(meth)acrylate; b) 15 to 50 wt %, based on the total weight of the pressure sensitive adhesive, of at least one synthetic rubber; and c) at least one tackifier compatible with the poly(meth)acrylate(s). The method further includes bonding the profile surface and the first adhesive side to one another, plasma-treating a second adhesive side of the layer of the pressure sensitive adhesive, and bonding the plasma-treated second adhesive side to the substrate surface.
