| 摘要 |
The invention relates to a linear UV polariser based on a polymerised mesogen being obtainable by curing by actinic radiation or by heat of a polymerisable composition which comprises the following components: a) a liquid crystalline component A composed of one or more achiral mesogenic compounds having at least one polymerisable end group optionally linked via a spacer group to the mesogenic core, b) a dichroic component B that absorbs light in the UV region, preferably with an absorption maximum between 320 and 440 nm, and is not polymerisable; and c) a photoinitiator or thermal initiator component C. |
