Marking based on modified chiral liquid crystal polymers |
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 first chiral liquid crystal state, applying to at least one area of the precursor composition a chiral dopant 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. |
