Abstract
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.
