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 llevarla a un estado de cristal líquido quiral, aplicar localmente al menos un agente modificador para modificar el estado de cristal líquido quiral y 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.
