摘要: The present invention relates to a marking on an item or substrate, which marking is based on a chiral nematic (also called cholesteric) liquid crystal precursor composition. Prior to curing the chiral liquid crystal precursor composition in the chiral liquid crystal state at least one optical property exhibited by the composition is modified by two modifying agents of different types in at least one area of the item or substrate.

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 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.
