  • Patent number: 10358600
    Abstract: A polymerizable LC material comprising at least one di- or multireactive mesogenic compound selected from the group of compounds of formula I, at least one monoreactive mesogenic compound selected from the group of compounds of formula II, wherein the parameter A11 to A21, L21, p, P11 to P22, R21, Sp11 to Sp21, X11 to X21, and Z11 to Z21 have one of the meanings as given in claim 1, and at least one carbazole oxime ester photoinitiator. Furthermore, a method for preparation of the polymerizable LC material, a polymer film with improved thermal durability obtainable from the corresponding polymerizable LC material, a method of preparation of such polymer film, and the use of such polymer film and said polymerizable LC material for optical, electro-optical, decorative or security devices.
