Abstract
The invention relates to an alignment layer with improved adhesion to liquid crystal (LC) films, to a precursor material used for the preparation of such a layer, to a laminate comprising such a layer and at least one LC polymer film, and to the use of the alignment layer and the laminate for optical, electrooptical, decorative or security uses and devices, wherein the alignment layer and the precursor material comprise at least one reactive mesogen in monomeric, oligomeric or polymeric form.
