ABSTRACT:
A process for printing or coating a substrate with a liquid-crystalline composition and at least one non-liquid-crystalline print or coating as a multilayer and a substrate produced by this process is described. The liquid-crystalline composition contains at least one compound having two polymerizable groups and at least one compound having only one polymerizable group, and optional further additives. The non-liquid-crystalline print or coating contains one or more IR- or UV-absorbent or fluorescent dye or pigment. The process and the printed substrate are useful in producing counterfeiting-proof marking of articles.
