Beschreibung
Zusammenfassung:	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.
