Polymerisable Liquid Crystal Material and Polymerised Liquid Crystal Film

Polymerizable LC material comprising at least one di- or multireactive mesogenic compound and one or more compounds of formula TRI,

• wherein
• R1 to R9 each denote independently from another a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 3 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, or an aryl group having 6 to 20 carbon atoms;
• Ra denotes a straight chain or branched alkyl having 1 to 20, which is optionally mono- or polysubstituted by F, Cl, Br, I or CN and 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—CO—, —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, and
• Rxx and Ryy each and independently of one another, denote H or alkyl having 1 to 12 C atoms.
