摘要：
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. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
