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.
