Title:
HOLOGRAM LAMINATED BODY, MANUFACTURE THEREOF AND HOLOGRAPHIC DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3799729
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To reduce decrease in display luminance and a change in a color tone by reducing a change in a regenerative wave length to an environmental temperature change by heat-treating one surface of a hologram.
SOLUTION: A hologram laminated body 10a is constituted of a laminated body composed of a base material 13, a pressure sensitive adhesive 12, a hologram 11, a barrier film 14', an adhesive 15 and a base material 13'. The pressure sensitive adhesive 12 is interposed between the hologram 11 and the base material 13. In this way, the pressure sensitive adhesive 12 comes into contact with the hologram 11 as a contact object medium, and the hologram 11, the pressure sensitive adhesive 12 and the base material 13 are also heat-treated in a condition where the base material 13 is laminated. That is, a using time malfunction in an environment where a temperature change exists by moving a volatile component substance contained in the hologram 11 after an exposure from the inside of the hologram by heat treatment. A volatile component inside of the hologram duffuses in the pressure sensitive adhesive, and a thermal expansion characteristic of the hologram 11 is improved, and the hologram 11 on which a regenerative wave length hardly changes even if an environmental temperature changes, can be obtained.
