Marking based on chiral liquid crystal polymers

Abstract

A liquid crystal polymer marking is obtainable by a process that comprises applying a chiral liquid crystal precursor composition onto a substrate, heating the composition to a bring same to a chiral liquid crystal state, locally applying at least one modifying agent to modify the chiral liquid crystal state, and curing and / or polymerization the resultant product.
