发明名称 CHIRAL LIQUID CRYSTAL POLYMER MARKING
摘要 A liquid crystal polymer marking is obtainable by a process that comprises applying a first chiral liquid crystal precursor composition onto a substrate, heating the composition to bring same to a first chiral liquid crystal state, applying to at least one area of the first composition a second chiral liquid crystal precursor composition, heating the at least one area to bring same to a second chiral 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.
