POLYMERFILM AUS FLÜSSIGKRISTALL MIT VERBESSERTER STABILITÄT

摘要

The invention reports on the use of multi-reactive polymerizable surfactants in mixtures of polymerizable mesogenic materials. The polymerizable surfactants are readily polymerized into the liquid crystal film and build a protective topcoat layer. The invention also relates to a method of producing polymeric optical films with improved stability by using the surfactants. Uses of these films are given for various applications including security applications and displays.
