Claim 0:
1. A polymerizable LC material comprising at least one multireactive mesogenic compound, one or more compounds of formula UVI, and optionally at least one monoreactive mesogenic compound,, wherein
R1 and R6 each and independently from another denote, H, halogen, —OH, —SH, —NRxxRyy—, —CO—Rxx—, —COORxx, —OCORxx, —OCO—ORxx, —S—CORxx, —CO—SRxx, —NRxx—CO—ORyy, —O—CO—NRxxRyy, —NRxx—CO—NRxxRyy, whereby one of R1 or R6 in formula UVI denotes —OH
R2 and R5 each and independently from another denote, H, halogen, —OH, —SH, —NRxxRyy—, —CO—Rxx—, —COORxx, —OCORxx, —OCO—ORxx, —S—CORxx, —CO—SRxx, —NRxx—CO—ORyy, —O—CO—NRxxRyy, —NRxx—CO—NRxxRyy,
R3 and R4 each represent a hydrogen atom, a hydroxy group, or a halogen atom,
Rxx and Ryy each, independently of one another, denotes H, alkyl having 1 to 12 C atoms, in which, in addition, one or more non-adjacent CH2 groups may each be replaced, independently of one another, by —O—, —S—, —NH—, —NRxx—, —SiRxxRyy—, —CO—, —COO—, —OCO—, —OCO—O—, —S—O—, —CO—S—, —NRxx—CO—O—, —O—CO—NRxx—, —NRxx—CO—NRyy—, —CH═CH— or —C≡C— in such a way that O and/or S atoms are not linked directly to one another,
having a content of multireactive mesogenic compounds plus any optional monoreactive mesogenic compounds of 30-99.9% based on the material.
