Polymerizable Liquid Crystal Material and Polymerized Liquid Crystal Film

A polymerizable LC material, comprising one or more reactive mesogenic compounds and one or more compounds of formula I

• wherein
• R1 to R6 are each and independently straight-chain alkyl radicals having 1 to 40 C atoms or branched or cyclic alkyl radicals having 3 to 40 C atoms, which are unsubstituted or mono- or polysubstituted by F, Cl, Br, I or CN and in which one or more non-adjacent CH2 groups may each be replaced, independently of one another, by —C(Rx)═C(Rx)—, —C≡C—, —N(Rx)—, —O—, —S—, —CO—, —CO—O—, —O—CO—, —O—CO—O— in such a way that O and/or S atoms are not linked directly to one another,
• Rx denotes H, halogen, a straight-chain, branched or cyclic alkyl chain having 1 to 25 C atoms, in which, in addition, one or more non-adjacent C atoms may be replaced by —O—, —S—, —CO—, —CO—O—, —O—CO—, —O—CO—O—, and in which one or more H atoms may be replaced by fluorine,
• and
• x and y are each independently ≥1,
• m and n are each independently ≥1.
