The present invention relates to polymerizable liquid crystalline formulations and especially to an ink formulation for inkjet printing comprising 10 to 50% w/w of one or more polymerizable liquid crystalline compounds and 50 to 90% w/w of one or more organic solvents selected from the group of aliphatic ketones, cyclic ketones, alkyl ethers of ethylene glycol or propylene glycol, alkyl esters of menthyl or aromatic solvents.

Polymerizable liquid crystal ink formulations

An optical component and a electro optical devices comprising the optical component. Further, a cholesteric polymerizable liquid crystalline (LC) material, preferably utilized in an optical component in accordance with the present invention, a process for the production of the cholesteric polymerizable LC material, a process to convert the cholesteric polymerizable material into a polymer film, a polymer film obtainable from the cholesteric polymerizable LC material, and the use of the polymer films in an optical component or device comprising a polymer film.

Polymerizable LC material and polymer film

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
