LIQUID-CRYSTALLINE COMPOSITION

摘要

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.
