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 chiral liquid crystal state, applying to at least one area of the precursor composition a modifying composition, if necessary, heating the at least one area to bring same to a modified liquid crystal state, and subsequently curing and/or polymerizing 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.
