Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung bahnförmiger Materialien mit einer Reliefstruktur, wie einer Beugungsstruktur. Hierfür wird zumindest bereichsweise ein Substrat (1) mit einer strahlungshärtbaren Lackschicht (2) beschichtet. In diese Lackschicht wird die Reliefstruktur eingebracht, wobei die Lackschicht (2) zum Zeitpunkt der Einbringung im Wesentlichen einen Härtungsgrad unterhalb des Gelpunktes aufweist.

Figure imgaf001
The invention relates to a method for producing sheet-like materials having a relief structure, such as a diffraction structure. For this purpose, a substrate (1) is at least partially coated with a radiation-curable lacquer layer (2). In this lacquer layer, the relief structure is introduced, wherein the lacquer layer (2) at the time of introduction substantially has a degree of cure below the gel point.
