Title:
ポリマー層を有する膜
Document Type and Number:
Japanese Patent JP4674233
Kind Code:
B2
Abstract:
The invention concerns a film, in particular a stamping film, laminating film or sticker film, which has at least one anisotropic polymer layer of an at least partially oriented liquid crystal material. The anisotropic polymer layer has one or more first regions which form a first security feature and in which the anisotropic polymer layer has properties which linearly polarise or which rotate the direction of rotation, and one or more second regions which form a second security element and in which the anisotropic polymer layer has circularly polarising properties. The first security feature is visualised when viewed through a first polariser and the second security feature is visualised when viewed through a second polariser responsive to a different polarisation state from that of the first polariser.
