    摘要: A hologram has a hologram element 3 containing a photopolymer and a cover film 22 and cover plate 21 which cover its surfaces. An adhesive 1 is used for bonding the cover film to the hologram element and the cover plate to the hologram element. The hologram has excellent humidity resistance, chemical resistance, solvent resistance and heat resistance, prevents coloration, can maintain its holographic properties and allows easy repositioning of the hologram element.

    摘要: A hologram element includes an optically transparent base plate having first and second opposite surfaces. A film of a diffraction grating is provided on the first surface of the base plate. A nonreflective member is provided on the second surface of the base plate via a dipping process. The nonreflective member includes one of a film including SiO.sub.2 particles and a film of MgF.sub.2. It is preferable that the SiO.sub.2 particles have diameters of 10-150 nm. The diffraction grating film includes, for example, one of a gelatine film, a photopolymer film, and a photoresist film. The base plate includes, for example, a flexible resin film. It is preferable that the flexible resin film is made of a material selected from the group consisting of amorphous polyolefine, polycarbonate (PC), polymethyl methacrylate (PMMA), and perfluoroalkoxypolyethylene (PFA).
