    Abstract: The invention relates to liquid crystalline substance mixtures which contain at least one compound selected from the group consisting of the compounds of the formula (Ia): Z1-Y1-A1-Y3-M1-Y4-A2-Y2-Z2 and of the formula (Ib): Z3-Y5- A3- Y7-M2-P, wherein the variable P means hydrogen, C1-C15-alkyl or a -Y8-A4-Y6- Z4 group, Z1 to Z4 polymerisable groups, Y1 to Y8 linking groups, A1 to A4 spac er and M1 and M2 mesogenic groups. Said liquid crystalline mixtures of substanc es optionally contain further additives selected from photoinitiators, reactive diluents and diluents, auxiliaries, colourants and stabilisors. The inventio n also relates to the use of such liquid crystalline mixtures of substances as printing ink, for printing or coating substrates, in electrooptic components , for forgery-proof marking of objects and for producing films or coatings.

    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.
