The present invention relates to a photo-polymerized, patterned or unpatterned liquid crystal polymer, especially a liquid crystal polymer film or a liquid crystal polymer network, comprising thio-ether units of formula (I)  Further, this invention relates to a composition used for the preparation of that photo-polymerized liquid crystal polymer of the invention, to processes of the preparation of that liquid crystal polymer and to its use.

Patternable liquid crystal polymer comprising thio-ether units

A diamine compound of formula (I) is proposed as well as polymers, copolymers, polyamic acids, polyamic acid esters, or polyimides based on such compound.

Photocrosslinkable materials

This invention relates to a birefringent layer, wherein the direction of the optical axis varies along the thickness direction of the layer, comprising I) 

Volume photo-aligned retarder

The invention relates to polarized and abrasion-resistant article comprising: a) a polarized layer applied to a substrate, said polarized layer including an oriented liquid crystal polymer layer (LCP) including at least one dichroic dye, said liquid crystal layer being coated on a photo-orientation layer, and b) an abrasion-resistant coating applied to the polarized layer on said substrate. The invention also relates to a process for manufacturing said articles, and to the use of the above-mentioned article for the manufacturing of optic glasses or lenses.

Polarized and abrasion-resistant optical article and process for manufacturing thereof

A diamine compound is proposed as well as polymers, copolymers, polyamic acids, polyamic acid esters, or polyimides based on such compound. The compound is represented by one of the general formulae (Ia) and (Ib). It could be shown that such structures, in particular for a specific choice of the residue B, provide, if e.g. used as orientation layers, a photostable, vertically aligning material with an improved VHR.

Compensation of a liquid crystal display can be achieved using a compensation structure, having, in the following order: a) a first o-plate; b) a first retarder; c) a liquid crystal cell; d) a second retarder; and e) a second o-plate. The first and second retarders can be c-plates or biaxial retarders.
