SURFACE RELIEF MICROSTRUCTURES, RELATED DEVICES AND METHOD OF MAKING THEM |
摘要 |
The present invention relates to a method for the replication of a patterned surface relief microstructure, comprising the steps of generation of a first layer with a patterned surface relief microstructure, generation of a master, by copying the microstructure of the first layer into a second layer, thereby involving at least one dry or wet etching step, characterized by an additional step, in which the microstructure of the master is brought into contact with a replica material, such that the microstructure of the master is reproduced in the replica. The invention further relates to the elements made as a replica according to the method. The surface relief microstructures are suitable to display images with a positive- negative and/or color image flip. The elements according to the invention are particularly useful for securing documents and articles against counterfeiting and falsification. |
