Abstract

marcação baseada em polímeros de cristal líquido quiral modificados. a presente invenção refere-se a uma marcação de polímeros de cristal líquido que é obtenível através de um processo que compreende aplicação de uma composição precursora de cristal líquido quiral sobre um substrato, aquecimento da composição para um primeiro estado de cristal líquido quiral, aplicação a pelo menos uam área da composição precursora de uma composição dopante quiral, aquecimento de pelo menos uma área para levar a mesma para um segundo estado de cristal líquido quiral, e subsequentemente cura e/ou polimerização do produto resultante.
