Definitions

  • Holograms can be classified into several types according to the recording form of interference fringes, but can be typically divided into surface relief holograms and volume holograms.
  • the surface relief hologram has a fine uneven pattern formed on the surface of the hologram layer.
  • the interference fringes generated by the interference of light are three-dimensionally recorded in the thickness direction as fringes having different refractive indexes. Since the volume hologram is an image recorded by the difference in the refractive index of the materials, it is more difficult to reproduce than the surface relief hologram.
  • the color of the reproduced image from the volume hologram layer when observed at the incident angle of the first regenerated illumination light and the first observation angle is set as the first color
  • the incident angle of the second regenerated illumination light and the second When the color of the reproduced image from the volume hologram layer when observed at the observation angle of is the second color, and the second color is a color on the shorter wavelength side than the first color, the reproduction is performed.
  • the first color may be changed to the second color, and the observation angle is fixed.
  • the first color may be changed to the second color by changing the incident angle of the first regenerated illumination light to the incident angle of the second regenerated illumination light.
  • the resin layer is arranged in contact with the volume hologram layer.
  • the volume hologram layer shrinks and the interval between interference fringes becomes narrow, so that the reproduction wavelength of the volume hologram layer is narrowed. Can be shifted to the shorter wavelength side with respect to the recording wavelength at the time of recording interference fringes.
  • the reproduction wavelength of the volume hologram layer is usually in the visible light region, and is, for example, 380 nm or more and 780 nm or less.
  • the color of the reproduced image from the volume hologram layer may be any color recognizable by the human eye, for example, purple, bluish purple, blue, green, yellowish green, yellow, orange, red, magenta. Can be mentioned.
  • the color of the reproduced image is different between the resin layer forming region and the resin layer non-forming region.
  • the colors of the reproduced images in the resin layer forming region and the resin layer non-forming region are preferably colors having similar wavelengths, such as a combination of green and blue or a combination of blue and bluish purple or purple. ..
  • the reproduction wavelength of the volume hologram layer in the resin layer forming region is shifted to the short wavelength side during the production of the volume hologram laminate, the reproduction color in the resin layer forming region is higher than the above-mentioned recording wavelength.
  • the color on the short wavelength side is preferable.
  • the resin layer is arranged in contact with the volume hologram layer.
  • the volume hologram layer shrinks and the interval between interference fringes becomes narrow, so that the reproduction wavelength of the volume hologram layer is narrowed. Can be shifted to the shorter wavelength side with respect to the recording wavelength at the time of recording interference fringes.
  • a volume hologram layer is brought into contact with a resin layer containing a resin and a polymerizable compound to transfer the polymerizable compound of the resin layer to the volume hologram layer.
  • the reproduction wavelength of is can be shifted to the longer wavelength side with respect to the recording wavelength at the time of interference fringe recording.
  • the interference fringes are recorded on the volume hologram layer after the resin layer is arranged in contact with the volume hologram layer, the interference fringes are also recorded on the resin layer.
  • the resin layer does not contain thermoplastic organic fine particles.
  • Examples of the colored resin film include a resin film containing a colorant and a transparent resin film having a colored layer on one surface.
  • Example 1 (1) Preparation of First Film and Second Film First, the first film and the second film were separately prepared by independent steps.
