Abstract

L'invention porte sur un marquage de polymères cristaux liquides qui peut être obtenu par un procédé qui consiste à appliquer une composition précurseur de cristaux liquides chiraux sur un substrat, à chauffer la composition pour l'amener à un état cristal liquide chiral, à appliquer localement au moins un agent modificateur pour modifier l'état cristal liquide chiral et à faire durcir et/ou à polymériser le produit ainsi obtenu.
