  • Patent number: 7727680
    Abstract: The hologram recording sheet according to the invention is made up of a base film and hologram sensitive materials sensitive to different wavelength regions formed therein in a desired pattern, or a film and at least two hologram recording sensitive materials sensitive to different wavelength regions laminated on the film with a transparent plastic spacer layer located therebetween, thereby enabling the required diffraction light wavelengths to be recorded on the required sites without producing unnecessary interference fringes. At least two hologram recording sensitive materials sensitive to different wavelength regions are formed on different sites on a film in dotted or striped configuration, the size of which is up to 200 mm or at least twice as large as the thickness of the sensitive material layers, thereby enabling regions diffracting light of different wavelengths to be formed in the form of independent sets of interference fringes.

  • Patent number: 7318905
    Abstract: A decorative sheet (S) for in-mold decorating injection molding has a base sheet (1A) and a resin layer (2) formed on a surface of the base sheet (1A) to be brought into contact with an injection-molded molding and containing an acrylic-modified polyolefin resin. The acrylic-modified polyolefin resin is a resin composed by grafting-copolymerizing an acrylic monomer and/or an acrylic prepolymer on principal chains of a polypropylene resin. The decorative sheet (S) includes, for example, a base sheet (1A) of an acrylic resin, a decorative layer (3) of a binder resin and at least either an acrylic resin contained in the binder resin or a polyvinyl chloride-acetate resin, and a bonding layer (2) containing an acrylic-modified polyolefin resin. A primer layer (4) may be sandwiched between the bonding layer (2) and the decorative layer (3).

  • Patent number: 6762810
    Abstract: The invention relates to a liquid crystal display device which enables a visual field range to be made wide and luminance drops to be reduced, so that bright displayed images can be presented, and provides a liquid crystal display device comprising, in order from a side of backlight 11, backlight 11, scatter plate 12, and liquid crystal element 20, wherein a transmission type of hologram scatter plate 13 is located in front of a display surface of liquid crystal display element 20. Hologram scatter plate 13, because of having been fabricated by means of single-step or two-step exposure, enables light more or less scattered through scatter plate 12 to be limitedly scattered within a given wide visual field range, so that bright displayed images can be presented over a wide visual field range yet with a reduced luminance drop. Scatter plate 12 may be omitted.
