Abstract

Un marcado de polímero de cristal líquido se puede obtener mediante un proceso que comprende aplicar una composición precursora de cristal líquido quiral en un sustrato, calentar la composición hasta un primer estado de cristal líquido quiral, aplicar a al menos un área de la composición precursora una composición dopante quiral, calentar al menos un área para llevarla hasta un segundo estado de cristal líquido quiral y luego curar y/o polimerizar el producto resultante. Este resumen no pretende definir la invención descrita en la presente memoria descriptiva ni limitar de modo alguno el alcance de la invención.
