Suggested are new adhesion promoters, which are particular suitable for use in displays. Its inclusion in the polymerisable LC mixture results in an excellent adhesion on substrate without colouration over time i.e. compared to amino siloxanes. The new additives have no effect on alignment of LC on the substrate while improving the adhesion.

UV curable adhesion promoters based on functionalised polyvinyl alcohols

The present invention relates to a method for the preparation of a homogeneous aligned liquid crystal polymer film, a polymer film obtainable from the corresponding method of production, and to the use of such polymer film for optical components and electro-optical decorative, as well as to components and devices comprising such polymer film.

Method for the preparation of a liquid crystal polymer film

The use of functionalized polymerizable polyvinyl alcohol as a binder or matrix for a dispersion of nanoparticles, wherein the nanoparticles respectively comprise a polymeric shell and a core containing a liquid crystalline medium. Composites comprising the functionalized polymer and the nanocapsules, methods for preparing the composites and electro-optical devices containing such composites.

Compositions comprising functionalized polyvinyl alcohol and nanocapsules containing a liquid crystalline medium

The invention relates to cinnamic acid derivatives of formula S wherein the radicals have the meaning indicated in claimto a process for their preparation and their use as self assembling photoalignment agent in liquid crystal mixtures. The invention further relates to a process for the fabrication of a liquid crystal (LC) display device with homogeneous alignment by photoaligning a liquid crystal mixture with positive or negative dielectric anisotropy comprising one or more compounds of formula S and optionally a polymerizable compound, to the liquid crystal mixture comprising the self assembling photoaligning agent and optionally the polymerizable compound and to the LC display produced by said process.
