<P>PROBLEM TO BE SOLVED: To provide a gas barrier sheet material which enables easy refuse disposal by reducing the amount of aluminum to be used, enables a high-accuracy formation of hologram fine irregularities, and can be produced efficiently without needing high-temperature heating, and to provide a method for production of the gas barrier sheet material. <P>SOLUTION: The gas barrier sheet material is produced through the processes of: forming a photo-curing resin layer 2 on a sheet-like substrate 1 by applying the photo-curing resin; covering on the photo-curing resin layer, a light-transmissive plate film on which a hologram fine irregularities are formed in such a state that the fine irregularities stick fast to the resin layer to transfer the hologram fine irregularities 4' on the surface of the resin layer by light-irradiating through the plate film in the above state and curing the resin layer; peeling the plate film after transfer of the hologram fine irregularities; and forming the gas barrier layer 7 by vapor depositing aluminum on the surface of the photo-curing resin layer side of the substrate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
