生産には向かない欠点がある。As a recording material for holograms, silver salt photosensitive materials with high release strength are generally used, but this material is expensive and difficult to photograph or reproduce, making hologram products expensive and requiring development, etc. It has the disadvantage that it is not suitable for mass production because it requires processing.

This method has the disadvantage that molding takes a long time because it is necessary to heat and press the thermoplastic resin and then cool it below the thermal deformation temperature.
さらに金型も高温にさらされるため金型の表面が酸化し
ホログラムの凹凸形状が変化し、ホログラムの再現性を
悪化させる問題もあった。Furthermore, since the mold is also exposed to high temperatures, the surface of the mold is oxidized, causing changes in the uneven shape of the hologram, resulting in a problem of deteriorating the reproducibility of the hologram.

ものであれば使用しうる。First, the mold having the uneven shape of the relief hologram may be manufactured by a known method. To explain this using a Fresnel hologram as an example, an argon laser beam is split using a beam splitter (eight mirror), one beam is guided to a photoreceptor coated with photoresist on a substrate, and the other beam is After exposing it to the same photoreceptor and allowing the two to interfere with each other, it is developed with a prescribed developer to form a relief hologram, and the hologram surface is coated with silver on the nail to a thickness of 400X. After performing nickel plating to a thickness of 1 mm using the resulting silver evaporated film as an electrode, the plating order was peeled off to form a mold with an uneven shape that was the reverse of the relief hologram. Since it is made of metal, it is strong and can be stably reproduced in large numbers. Alternatively, materials other than nickel plating may be used as long as they have resistance to resin liquid C, mechanical strength, and durability against ultraviolet rays or electron beams.

Furthermore, resin liquids that can be cured by ultraviolet rays and electron beams include seven polymers, oligomers, and prepolymers that have unsaturated bonds in their molecules, as well as mixtures of epoxy compounds and Lewis acids. You can use it in addition.

の塗布厚みがあれば良い。As a method for applying this resin liquid that is cured by ultraviolet rays or electron beams to the mold or support, known methods such as roll coating, knife coating, Myaber coating, gravure coating, screen printing, and pouring can be used. The coating thickness is sufficient as long as the relief hologram original plate and the support are in close contact with each other, and is usually 1μ to 1000μ.
It is good if the coating thickness is .

しうる。Irradiation with ultraviolet rays or electron beams can be performed through the support, but it is also possible to irradiate through the mold if the mold is made of a material that transmits ultraviolet rays or electron beams. Note that the present invention applies to Fresnel holograms, Fourier transform holograms,
It can be applied to any hologram such as a Fraunhofer hologram, and can also be applied to R and general diffraction gratings such as image holograms, rainbow holograms, holographic stereograms, etc. that utilize these hologram formats.

方法によれば、低温で複製が可能であり、又、複製材料

なへ、安定して大量のホログラムの複製が可能となる。According to the above-described method of the present invention, the resin liquid that is cured by ultraviolet rays or electron beams is shaped at the same time as it is cured, so that it is possible to perform duplication in a short time without requiring steps such as cooling. Father, with this method, it is possible to reproduce holograms at low temperatures, and since the reproduction material is soft to the touch, the original plate such as the mold will not be damaged, and a large number of holograms can be reproduced stably. It becomes possible.

脂と支持体とを一体化させることにより薄くても強度の
あるホログラムを製造しうる。In addition, if a resin that is cured by ultraviolet rays or electron beams is used alone, the strength of the resulting hologram is weak, and only a thick hologram can be made by applying a large amount of resin liquid that is cured by ultraviolet rays or electron beams, and it is difficult to apply a thick resin liquid. However, in the present invention, a thin but strong hologram can be manufactured by integrating a support with a resin that is cured by ultraviolet rays or electron beams.

電子線で硬化する樹脂を硬化できる利点もある。In addition, the amount of resin liquid used can be reduced as long as it has enough strength to bring the support and original plate into close contact. Since the resin, which is cured by ultraviolet rays or electron beams, is sandwiched between the mold and the support, it is possible to eliminate the influence of oxygen in the air, which can inhibit the curing of the resin, and to efficiently cure the resin by ultraviolet rays or electron beams. It also has the advantage of being able to harden resins that can be hardened with electron beams.

フホログラムを得た。First, the mold surfaces of a mold having the reverse shape of a relief hologram manufactured by a conventional method are placed on the coating surface, and then passed between a pair of pressure rolls to make them come into close contact with each other, and an ultra-high pressure mercury lamp is applied from the film side. When the resin liquid was cured by applying ultraviolet rays and the mold was peeled off, a relief hologram integrated with the film was obtained.
