Abstract (en)
[origin: EP1527902A2] Method for preparing a material (A), in the form of an endless belt, having a relief structure, preferably a diffraction structure. Method for preparing a material (A), in the form of an endless belt, having a relief structure, preferably a diffraction structure, comprises coating a substrate, at least on some regions, with a layer of radiation-hardenable lacquer (I) and forming the relief structure in (I). The new feature is that, up to the time when the structure is formed, (I) has a degree of hardness below the gel point. Independent claims are also included for the following: (1) (A) produced by the new method; (2) safety element prepared using (A); (3) safety document that includes an element of (2); and (4) apparatus for preparing (A).
