The invention relates to new reactive mesogenic compounds (RM), polymerisable liquid crystal (LC) mixtures and polymers comprising them, and the use of the compounds, mixtures and polymers in optical, electrooptical, electronic, semiconducting or luminescent components or devices, in decorative, security or cosmetic applications, especially for use in polymer films having high optical dispersion.

Reactive mesogenic compounds and mixtures

The invention relates to a liquid crystal (LC) material that aligns homeotropically on substrates with high or low surface energy.

LC material with homeotropic alignment

The invention relates to a negative birefringent retardation film comprising polymerised liquid crystal (LC) material with helically twisted structure and planar orientation, its use in compensators and electrooptical displays like liquid crystal displays, and to compensators and liquid crystal displays comprising such a negative retardation film.

Negative retardation film

The invention relates to a birefringent marking comprising a liquid crystal material. The invention further relates to method of providing such a birefringent marking and to the use of the birefringent marking for decorative or security applications.

Birefringent marking

The invention relates to a process of preparing films and multilayers comprising polymerized liquid crystal material with uniform orientation, to films and multilayers obtained by said process and their use for optical and electrooptical applications.

Process for preparing films of polymerized liquid crystal material having a first film of a polymerized liquid crystal material with uniform orientation and a second film of a polymerized liquid crystal material with uniform orientation directly on the first film

A birefringent film comprising at least one birefringent layer of liquid crystal material forming multi domains with a splayed structure may be coated onto a reflective substrate, e.g., with an aluminium surface. The birefringent film is particularly suited for decorative, security, authentification or identification applications.
