Application to substrates of elements or films which have a surface relief pattern providing an optically variable effect

摘要

A film or element (12, 14, 15) having an optically variable pattern or relief is applied to a substrate (20), without the use of heat, by use of a contact or non-heat-curable adhesive (30) applied to the film or element (12, 14, 15) or to the substrate (20) and then bringing the two into contact with one another.
