Problems solved by technology

Lenses produced by this holographic method have a number of disadvantages, far from the fact that when it comes to lenses having a round or preferably elliptical shape, the holographic production has a lens effect with relatively little technical effort. The diffractive optical structure is possible
A disadvantage of producing lenses with holography is that, for example, they do not appear to be too bright externally, and in general they appear irregular, especially in the central area, so the visual effect that the lenses should produce is significant reduce
Another downside of holographically produced lenses is that it's practically impossible to achieve certain color effects with any great design freedom.

Embodiment Construction

[0025] exist figure 1 In a diagrammatic cross-sectional view of , it shows that the thin-layer configuration according to the invention comprises two thin layers of material 1 and 2, between which an interface 3 is formed, which may be metallized, for example, and this may be achieved by, for example Said to be obtained by vacuum metal vapor deposition. For some applications, the thin layers 1 and 2 of material can be formed with air. exist figure 1The diameter of the middle lens is plotted in arbitrary units along the X-axis, since the exact size or diameter of the lens structure is irrelevant. In general, however, the diameter of the lens structure is between 0.5 and 300 mm, preferably between 3 and 50 mm, and the focal length is usually between the value of the lens diameter and 5 times this value.

[0026] exist figure 1 On the Y-axis of , the thickness of the thin layer of material 1, 2, ie the height of the structure, is given using the value representing the phase d...

Abstract

A layer arrangement is proposed, particularly for transfer films or laminated films, which exhibits at least two superposed synthetic resin layers, between which there is provided an interface surface having a refractive structure producing a lens-like effect, the novelty claimed being a special design of the structure having a diffractive effect.

Description

technical field [0001] The present invention relates to an arrangement of thin layers, in particular for the realization of transport thin layers or laminated thin layers, which exhibit at least two superimposed material layers, in use, at least the (or these) facing viewer Thin layers of material have a transparent or translucent appearance and form boundaries between them which exhibit, at least in one region thereof, a diffractive optical structure producing a certain, either magnifying or non-magnifying, lens-like effect. Background technique [0002] In this sense, transfer films include in particular so-called relief films, which consist of a base film and a transfer film which can be separated from the base film for transfer to a substrate. Usually, the transfer film of this embossed film is composed of thin layers of varnish, and in the present invention, it means that the term "material layer" mainly refers to a thin layer of varnish, but sometimes also refers to an...
