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 à un premier état cristal liquide chiral, à appliquer sur au moins une zone de la composition précurseur une composition de dopant chiral, à chauffer ladite ou lesdites zones pour les amener à un second état cristal liquide chiral et, par la suite, à faire durcir et/ou à polymériser le produit ainsi obtenu.
