  Disclosed is a substrate which has thereon a marking or layer comprising a cured chiral liquid crystal precursor composition which does not contain any salt that would change the position of a selective reflection band exhibited by the cured composition. A modifying resin made from one or more polymerizable monomers comprising an average of at least one ether functionali typer polymerizable group 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 changes the position of a selective reflection band exhibited by the cured chiral liquid crystal precursor composition on the substrate in the one or more areas.

  本发明公开了一种基底，该基底上有一个包含固化手性液晶前驱体组合物的标记或层，该组合物不含任何会改变固化组合物所显示的选择性反射带位置的盐。改性树脂由一种或多种可聚合单体制成，这些单体平均含有至少一个醚官能团型可聚合基团，被置于基底和标记或层之间，并在一个或多个区域与标记或层接触。改性树脂可改变固化手性液晶前驱体组合物在基底上一个或多个区域中显示的选择性反射带的位置。

  The present invention is related to the filed of optically variable security elements comprising a region based on a single cured ink comprising a cholesteric liquid crystal polymer, said region having at least two, preferably at least three, patterns exhibiting, at at least one viewing angle, a different CIE (1976) color index parameter and/or a different position of the selective reflection band for protecting security documents against counterfeiting and/or illegal reproduction. In particular, the present invention relates to processes for manufacturing said features, when the processes comprises the steps of a) applying on a substrate by a rotogravure process with the use of a gravure cylinder having at least two, preferably at least three, different engravings a single cholesteric liquid crystal precursor composition, b) heating the applied composition to bring said composition to a cholesteric liquid crystal state, and c) curing the composition so as to form the region based on a single cured ink comprising a cholesteric liquid crystal polymer.

  本发明涉及光学可变防伪元件，该元件包含一个基于胆甾液晶聚合物的单一固化油墨的区域，所述区域具有至少两个，最好是至少三个图案，在至少一个视角下显示不同的CIE（1976）色指数参数和/或选择性反射带的不同位置，用于保护防伪文件免受伪造和/或非法复制。特别是，本发明涉及制造上述特征的工艺，该工艺包括以下步骤：a) 使用凹版滚筒，通过凹版印刷工艺在基底上涂布至少两种（最好至少三种）不同雕刻的单一胆甾型液晶前体组合物；b) 加热涂布的组合物，使所述组合物达到胆甾型液晶状态；以及 c) 固化组合物，以形成基于包含胆甾型液晶聚合物的单一固化油墨的区域。
