摘要： A magnetic card of the invention comprises a card substrate 11 on which a magnetic layer 12, a thin-film layer 13 formed of a metal or a metal compound for concealing the magnetic layer, a printed layer 14 and a volume hologram layer 15 are successively provided, wherein magnetic information is recorded on or read from a volume hologram layer side. The volume hologram layer 15 is composed essentially of a photosensitive material comprising a cationic polymerizable compound, a radical polymerizable compound, a photo-radical polymerization initiator system that is sensitive to light of a specific wavelength to polymerize the radical polymerizable compound, and a photo-cationic polymerization initiator system that is less sensitive to the light of a specific wavelength but sensitive to light of another wavelength to polymerize the cationic polymerizable compound. The magnetic card is improved in terms of wear resistance to sliding contact with a magnetic head, and ensures precise writing or reading of magnetic recording data, with improved ability to prevent forgery.

摘要： In the multilayer volume hologram 1 of the invention, the adhesive layer 5, volume hologram 6 and surface protective film 7 are laminated on the application member 2 in this order, and the breaking strength of the hologram layer should be larger than the peel strength between the surface protective film and the volume hologram layer and smaller than the peel strength with which the hologram layer is peeled off the application member and the breaking strength of the surface protective film. This multilayer volume hologram provides a more improved protection for the volume hologram. A portrait replacement or falsification of an information area ensures that the volume hologram layer can break down. Thus, more reliable counterfeit-proofness is achievable.

摘要： The invention provides a hologram transfer foil comprising a substrate and a transfer layer laminated thereon, said transfer layer comprising a surface protective layer, a thermoplastic resin layer, a hologram layer and a heat seal layer in this order. The hologram transfer foil is applied on the heat seal layet side to an application member. In this case, a peel force between the substrate and the surface protective layer is smaller than that between adjacent layers in other layers. This hologram transfer foil enables a hologram image, etc. to be reconstructed in an uninterrupted manner, and is improved in terms of transferability and productivity.
