【発明の詳細な説明】
本発明は表面に微細な凹凸形状を賦与して情報を配録す
るレリーフホログラムの歇産に適した複製方法に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reproduction method suitable for the continuous production of relief holograms in which information is recorded by imparting fine irregularities to the surface.
ホログラムは、一般に光の干渉のパターンｌｅ録したも
のであり、三次元画像の記録をはじめ。A hologram is generally a recording of a pattern of light interference, and can be used to record three-dimensional images.
高密度な情報記録が可能である特性を利用して光メモリ
ー等多方面への応用が期待されている。Taking advantage of its ability to record high-density information, it is expected to be applied to many fields such as optical memory.
ホログラムの記録材料としては、高解像力の銀塩感光材
料が一般に用いられるが、この材料は高価であり、また
撮影あるいは複製も困難であるため、ホログラム製品は
高価格となり、また現像等の処遅を必要とするため大量
生産には向かない欠点がある。High-resolution silver salt photosensitive materials are generally used as recording materials for holograms, but this material is expensive and difficult to photograph or reproduce, making hologram products expensive and slow in processing such as development. It has the disadvantage that it is not suitable for mass production because it requires
一方、レリーフホログラムの場合は、フォトレジスト等

可塑性樹脂等に型押しすることにより、簡単且つ大量に
複製が作れるということが知られているが、この方法で

に冷却する必要があるため、成型に時間を要する欠点が
あった。On the other hand, in the case of a relief hologram, the hologram information is recorded in a pattern of concave and convex parts on a photoresist, etc., then this concave and convex pattern is molded by plating, etc., and this mold is embossed into thermoplastic resin, etc., making it easy to create. It is also known that large quantities of copies can be made, but this method has the disadvantage that it takes time to mold, as it requires heating and stamping the thermoplastic resin and then cooling it below the heat transformation 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が
悪化する問題もあった。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 in which the reproducibility of the hologram deteriorates.
本発明者はこれらの問題点に一対し、以下の方法を用い

子線を照射し、４？４１！８液を硬化せしめると共に賦
型するものである。The present inventor has found that these problems can be solved by using the following method. That is, in the present invention, a resin liquid that is cured by ultraviolet rays or electron beams is applied to a relief hologram original plate, and the coated surface is further irradiated with ultraviolet rays or electron beams to cure and shape the 4?41!8 liquid.
本発明の方法によれば紫外線又は電子線で硬イ［する樹
脂液は硬化と同時に賦型されるので、高エネルギーの紫
外線又は電子線を照射すれば短時間の複製が可能となる
上、低温での樹脂硬化ができて金型の酸化も回避でき、
複製材料も樹脂液を用いるので柔いため原版を損傷する
こともないという諸効果を奏する。According to the method of the present invention, the resin liquid that is hardened by ultraviolet rays or electron beams is shaped at the same time as it is cured, so it is possible to reproduce in a short time by irradiating high-energy ultraviolet rays or electron beams, and at low temperatures. It is possible to harden the resin and avoid oxidation of the mold.
Since the duplication material also uses a resin liquid, it is soft and has the advantage of not damaging the original.

The photoresist is exposed to light and developed with a predetermined solution (for example, in the case of the above-mentioned photoresist, AZ Depero, Par) K manufactured by the same company. Nickel plating is performed using the vapor-deposited film as an electrode to form a plating layer of about 1 mm thick.
