摘要:
A substrate having thereon a marking or layer comprising a cured chiral liquid crystal precursor composition which comprises at least one salt that changes the position of a selective reflection band exhibited by the cured composition compared to the position of a selective reflection band exhibited by a cured composition that does not contain the at least one salt. A modifying resin made from one or more polymerizable monomers is disposed between the substrate and the marking or layer and changes the position of the selective reflection band exhibited by the cured precursor composition comprising the at least one salt on the substrate in the one or more areas. 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.
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.
