Abstract
The present invention relates to a method for producing three-dimensional macroscopic patterns in liquid-crystalline coatings, patterned layers containing liquid-crystalline materials and produced by said method, and the use thereof in decorative and security products. In the method, the liquid-crystalline coating in a non-solidified state is brought into contact with a printing form for a relief printing method, with the result that depressions which are not deeper than 10 μm arise in the coating.
