    摘要： The present invention relates to a photoalignment composition comprising a) 0.001 to 20%, by weight, preferably, 1 to 10% by weight, more preferably 1 to 9% by weight of at least one photoreactive compound (I) that comprises a photoalignment group and b) 80 to 99.999% by weight, preferably, 90 to 99% by weight, more preferably 91 to 99% by weight of at least one compound (II) that does not comprise a photoalignment group, and c) optionally at least one reactive or non reactive additives, and d) optionally at least one solvent. Further the present invention relates to the use of this photoalignment composition for the alignment of liquid crystals or liquid crystal polymers, in electro-optical and optical elements, systems and devices.

    摘要： The invention relates to a method for the manufacturing of uniform and defect free liquid crystal aligning layers which comprises applying onto a substrate a composition having a viscosity in the range of 1 to 14 mPas, which comprises at least one liquid crystal photoalignment material and at least one solvent; or applying onto a substrate a composition comprising at least one liquid crystal photoalignment material and at least one surfactant, wherein the latter does not have any negative impact on the aligning properties. In addition, the present invention relates to the above-cited compositions and aligning layers, and to the use of these aligning layers for liquid crystal devices and optical or electro-optical components.
