摘要： The invention relates to a polymerisable LC material comprising at least one di- or multireactive mesogenic compound of formula T,

RT1-(AT1ZT1)m1-GT1-(ZT2-AT2)m2-RT2  T

and at least one compound of formula CO-1,





wherein the parameter are RT1, AT1, ZT1, m1, GT1, ZT2, AT2, m2, RT2, L1 to L3, R1 and R2, and n are defined as given in claim 1.

Furthermore, the present invention relates also to a method for its preparation, a polymer film with improved thermal durability obtainable from the corresponding polymerisable LC material, to a method of preparation of such polymer film, and to the use of such polymer film and said polymerisable LC material for optical, electro-optical, decorative or security devices.
