Abstract
The invention relates to a linear UV polarizer based on a polymerized mesogen obtained by curing with actinic radiation or heat of a polymerizable composition comprising: PA1 a) a liquid crystalline component A composed of one or more achiral mesogenic compounds having at least one polymerizable end group optionally linked via a spacer group to a mesogenic core, PA1 b) a dichroic component B that absorbs light in the UV region, with an absorption maximum of from 320 to 440 nm, and PA1 c) a photoinitiator or thermal initiator component C.
