The invention relates to a photopolymer formulation comprising specific aromatic glycol ethers as writing monomers, matrix polymers and a photoinitiator. The invention further provides an unexposed holographic medium obtainable using an inventive photopolymer formulation, and an exposed holographic medium obtainable by exposing a hologram into an inventive unexposed holographic medium. The invention likewise provides a visual display comprising an inventive exposed holographic medium, for the use of an inventive exposed holographic medium for production of chip cards, identification documents, 3D images, product protection labels, labels, banknotes or holographic optical elements, and specific aromatic glycol ethers.
本发明涉及一种光聚合配方,包含特定的芳香族乙二醇醚作为写入单体、基质聚合物和光引发剂。本发明还提供了一种使用创新光聚合配方可获得的未曝光全息介质,以及通过将全息图曝光到创新的未曝光全息介质中获得的曝光全息介质。本发明同样提供了一种包含创新曝光全息介质的视觉显示,用于创新曝光全息介质在生产芯片卡、身份证件、三维图像、产品保护标签、标签、钞票或全息光学元件中的应用,以及特定的芳香族乙二醇醚。
