МНОГОСЛОЙНЫЙ ЭЛЕМЕНТ ПО МЕНЬШЕЙ МЕРЕ С ОДНИМ СЛОЕМ, СОДЕРЖАЩИМ ЧУВСТВИТЕЛЬНЫЙ К ЛАЗЕРНОМУ ИЗЛУЧЕНИЮ МАТЕРИАЛ

摘要

FIELD: the invention refers to a multiplayer body. ^ SUBSTANCE: the multi-layer body fulfilled as a carbon film preferably as hot stamping film or as laminated film consists of layer structure formed with a substrate, a layer sensitive to laser emission where layered structure has one background layer which serves for laser emission as reflective and/or opaque , and/or absorbent which is correlated with a layer sensitive to laser emission. The background layer is located in one partial field on the side inverted to the layer sensitive to laser emission and provides so that laser emission does not pass or pass in a very insignificant degree into the layers below the background layer so that sufficient destruction of the substrate is averted under influence of used laser emission. ^ EFFECT: creation of multi-layer element that ensures possibility of forming exceptionally accurate and many-sided marking induced with laser. ^ 18 cl, 10 dwg
