| 摘要 |
<p>The invention relates to a substrate having thereon a marking or layer comprising a cured chiral liquid crystal precursor composition, wherein the chiral liquid crystal precursor composition comprises at least one salt that changes the position of a selective reflection band exhibited by the cured composition compared to a position of a selective reflection band exhibited by a cured composition that does not contain the at least one salt, and wherein a modifying resin made from one or more polymerizable monomers is disposed between the substrate and the marking or layer and in contact with the marking or layer in one or more areas thereof, the modifying resin changing a position of the selective reflection band exhibited by the cured chiral liquid crystal precursor composition comprising the at least one salt, on the substrate in the one or more areas.</p> |
