ターンを凹凸で成形しても得られる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for replicating a hologram. Holograms are usually made on silver salt photosensitive materials, but they can also be obtained by molding hologram patterns with irregularities.
すなわち、フォトレジストを塗布した乾板にホログラム

、ニッケルの面を露呈させ、成形用の型が得られる。That is, a hologram image is exposed to light on a dry plate coated with photoresist, and then developed to obtain a concavo-convex image on the dry plate. Thereafter, copper is deposited on the uneven surface forming this image to impart electrical conductivity. Next, nickel plating is applied using this copper surface as a negative electrode. After a nickel layer is electrodeposited to a thickness that can withstand handling, it is peeled off from the photosensitive material surface, and then, in order to provide conductivity, the deposited copper is melted away to expose the nickel surface, which is then placed in a mold for molding. is obtained.
銅を除去した型の表面には前述の露光・現像により得ら
れた凹凸面が凹凸逆になって複製されている。On the surface of the mold from which the copper has been removed, the uneven surface obtained by the above-mentioned exposure and development is duplicated with the unevenness reversed.
この面も、ホログラム像を形成することは、もちろんで
ある。Of course, this surface also forms a hologram image.
この様にして得られた型によって多数のホログラムを複
製する方法は、従来は熱可塑性樹脂を素材とし、これに
加熱回圧の熱リサイクルを適用する方法に依っていた。Conventionally, the method of replicating a large number of holograms using a mold obtained in this manner has relied on a method of using thermoplastic resin as a material and applying heat recycling by heating and pressure to the material.
例えば、０．２〜０．５龍の厚みの塩化ビニル樹脂を、
表面温度１１０〜１３０℃にした前記型に対し１５０〜
２００１９’ｄに加圧し、数秒から数１０秒間この状態
を保ち、而る後に前記型及び対盤を冷却して常温にする
。For example, vinyl chloride resin with a thickness of 0.2 to 0.5 mm,
150~150℃ for the above mold whose surface temperature was 110~130℃
Pressure is applied to 20019'd, this state is maintained for several seconds to several tens of seconds, and then the mold and counter plate are cooled to room temperature.
この際、当然成型された塩ビシートも常温になりている
ので、これを取り出すことによりホログラム複製版が得
られるのである。At this time, the molded PVC sheet is naturally at room temperature, so by taking it out, a hologram reproduction plate can be obtained.
以上は、従来の熱リサイクルによる成型の一例で、素材
としては塩化ビニル樹脂に限らず、アク可能ではない。The above is an example of conventional molding using heat recycling, and the material is not limited to vinyl chloride resin and is not acrylicable.
また前原の例のようにシート状にあらかじめ成形されて
いる樹脂を加圧成形するのではなく、熔融した樹脂を型
内に射出させるインジェクション成型による複製も可能
であった。In addition, it was also possible to reproduce by injection molding, in which molten resin was injected into a mold, instead of pressure molding a sheet of resin as in Maehara's example.
これらの方法は、すべて熱により可塑性を付与された樹
脂を成型するものであるが、いずれの場合においても、
成形された複製物をとり出す時の温度は常温に近いもの
でなくてはならない。All of these methods involve molding resin that has been given plasticity by heat, but in each case,
The temperature at which the molded replica is taken out must be close to room temperature.
従って型及び対盤は一回の成形毎に成形に必要な温度ま
で上昇させ、かつ一定の時間この温度を保ち、而る後に
常温近くまで冷却するという熱０・リサイクルによって
複製を行なっている。通常の場合このサイクルは２＠〜
６０秒を要している。Therefore, duplication is performed by zero-heat recycling, in which the temperature of the mold and counter-plate is raised to the temperature required for molding each time, maintained at this temperature for a certain period of time, and then cooled to near room temperature. Normally this cycle is 2@~
It takes 60 seconds.
一方、ホログラムの回折格子は１ ｍｍ当り１０００〜
３０００本という極微細な間隔で形成されているため従

形性は完全ではない。従って製品の収率も良くながった
。On the other hand, the diffraction grating of a hologram is 1000 ~
Because they are formed at extremely fine intervals of 3,000 lines, it is difficult to completely transfer and replicate the unevenness of the mold onto the molded product using conventional thermal recycling molding, and the moldability against the mold is generally not perfect. Therefore, the product yield also improved.
このように、従来の加熱・押圧・冷却というプロセスに
従えば、成型時間と成型性という欠陥を担っており、ホ
ログラムを製造する上で大きな問題となっている。As described above, if the conventional process of heating, pressing, and cooling is followed, it suffers from defects in molding time and moldability, which poses a major problem in manufacturing holograms.

以下に本発明の一実施例を図面に基づいて説明する。The present invention makes it possible to mold a hologram image by using a liquid or semi-solid resin that hardens by absorbing radiation, especially ultraviolet rays, without using such thermoformable resin. Ta. According to the method of the present invention, heating, pressing,
Compared to hologram images manufactured through a cooling process, the manufacturing time is significantly shorter, less energy is required for manufacturing, and they can be molded (duplicated) with extremely high precision.6 An embodiment of the present invention will be described below based on the drawings.

特殊な効果を求めることもできる。FIG. 1 is a schematic explanatory diagram showing a molding method according to the present invention. For example, materials such as vinyl chloride resin, acrylic resin, etc. that are obtained by the above-mentioned process and have low ultraviolet absorption are suitable, and in addition, it is preferable that the material has a refractive index approximately equal to that of the cured resin layer. Note that the base sheet is required to transmit ultraviolet rays, but it may be colored. in this case,
You can also request special effects.

By irradiating ultraviolet light in the 8oW11N region, particularly around 360mK, the monomer crosslinks the linear polymers to form a three-dimensional network structure. Examples of such prepolymers include epoxy acrylate, diurethane acrylate, and the like, and examples of hexamers include n-butyl acrylate and n-butyl methacrylate.

2) is pressed between the mold (4) and the base sheet (2) so that the ultraviolet curable resin is sandwiched between the mold (4) and the base sheet (2).

れ以下にすることも可能である。The highly fluid ultraviolet curable resin spreads on the top surface of the base sheet and is extended by 5 squares, and at the same time spreads in contact with the patterned surface (5) of the upper mold (4), and on the contact surface, it spreads into the patterned surface (5) of the mold (4). It fills up according to pattern (5). The thickness of the ultraviolet hard line curable resin layer is 1 to 70 μm, preferably 25 μm.
It is as follows. This is not only to save resin, but also to avoid deformation after molding. When irradiating ultraviolet light with a 2 kW ultra-high pressure mercury lamp and an irradiation distance of 25',
The time may be 2 to 5 seconds, and if the UV light is more intense, the time may be 1 second or less.

も従来の成形方法による製品に比べ数段向上している。The present invention has the above-described configuration, and when a hologram is produced by such a method, there is no need to recycle heat, which shortens the molding time and facilitates mass duplication. In addition, when the layer containing the uneven surface, that is, the ultraviolet curable resin layer, is completely crosslinked, the product has a higher hardness than ordinary thermoplastic resin, and therefore has a much higher scratch resistance than products made using conventional molding methods. It's improving.
また、その凹凸面の複製精度も極めて良好であるが、こ
れは、紫外線硬化型樹脂が液状で型のパターンによくな
じみ、そのまま成形されるからである。Furthermore, the reproduction accuracy of the uneven surface is extremely good, because the ultraviolet curable resin is liquid and blends well with the pattern of the mold, allowing it to be molded as is.

ない成形面が得られる。Furthermore, in the case of molding by thermal recycling, it is unavoidable that impurities or solidified resin etc. get mixed into the resin material, which results in defective products, but according to this method, the UV-curable resin is Since it can be filtered and even minute contaminants can be removed, a molded surface with almost no defects can be obtained.
なお用途によっては、本方法によって成形した面に真空

かなり高価なものであるが、本発明では成形層に、ごく
薄い層としてのみ使用するものであるので、コスト的に
は十分見合うものである。The hologram according to the present invention has a two-layer structure consisting of an ultraviolet curable resin layer (the unevenness is in this part) and a base sheet.
Although it is quite expensive, in the present invention it is used only as a very thin layer in the molding layer, so it is well worth the cost.

らない。In addition, since the stand used for viewing transmission holography has a two-layer structure, refraction occurs at the boundary between the two layers. For example, the refractive index of ★ is t54 in the case of salt, and 1.49 in the case of acrylic resin, so it is not a substantial problem.
