    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： A novel photoactive copolymer and its use as orientation layers for liquid crystals and in the construction of unstructured and structured optical elements and multilayer systems. The copolymer contains side chains incorporating photoreactive groups and simultaneously side chains of general formula (I) wherein the total number of rings, including the number of rings in optionally present condensed systems is at least two and at most six; wherein the broken line symbolizes the point of linkage to the polymer main chain; and wherein the variables are defined in the disclosure.
