【発明の詳細な説明】 〔産業上の利用分野〕 本発明は透過型ホログラム用の記録材料に関するもの
である。Description: TECHNICAL FIELD The present invention relates to a recording material for a transmission hologram.
ホログラムは情報を帯びた光の波面を記録する技術で
あり、通常は板、フィルル等の基材上に設けられたホロ
グラム記録層に情報光と参照光との干渉縞を透過率もし
くは屈折率もしくは凹凸の分布の形で記録している。A hologram is a technology for recording the wavefront of light carrying information.Usually, a hologram recording layer provided on a substrate such as a plate or a film is used to transmit interference or fringe of interference fringes between information light and reference light. It is recorded in the form of a distribution of irregularities.
第２図は従来のホログラム記録材料を示す図である。
図中、１はホログラム記録材料、２はホログラム記録
層、３は光透過性材料４はハレーション防止層である。FIG. 2 is a view showing a conventional hologram recording material.
In the figure, 1 is a hologram recording material, 2 is a hologram recording layer, 3 is a light transmissive material, and 4 is an antihalation layer.

る。In the figure, two light beams irradiated to the recording layer 2
5 and 6 form interference fringes and are recorded on the hologram recording layer 2. At the same time, the light transmitted through the hologram recording layer 2 transmits through the light transmitting material 3 and is absorbed by the antihalation layer 4.

して不要な干渉縞を発生し、これが再生像中に表れて再
生像の質を低下させてしまうという問題があった。Incidentally, the antihalation layer 4 is required to have the same refractive index as the light transmissive material 3, not to be reflected at the interface, and to have light absorbency with respect to the wavelength of light to be used. However, in general, it is difficult to satisfy these two conditions at the same time.
At present, the refractive index of the anti-halation layer 4 does not completely match. For this reason, reflection occurs at this interface, and a repeated reflection 7 as shown in FIG. 3 occurs, and the repeated reflections 7 or the repeated reflections 7 and the incident light beams 5 and 6 interfere with each other to generate unnecessary interference fringes. This has been a problem in that it appears in the reproduced image and deteriorates the quality of the reproduced image.

ことができる。The hologram recording material of the present invention is obtained by matting at least one surface of a light-transmitting material layer or a light-absorbing material layer below the hologram recording layer, so that extra light transmitted through the hologram recording layer is matted. Even if the light is scattered and reflected, it is a scattered reflection, so that unnecessary interference fringes do not occur, and the image quality of the hologram reproduced image can be improved.
以下、本発明を実施例に基づいて説明する。 Hereinafter, the present invention will be described based on examples.

料、10は光吸収性材料である。FIG. 1 is a view showing a hologram recording material according to one embodiment of the present invention, and the same numbers as those in FIG. 2 indicate the same contents. In the drawing, reference numeral 8 denotes an adhesive layer, 9 denotes a light-transmissive material processed by matting, and 10 denotes a light-absorbing material.

黒ラッカースプレーを使用した。In the present embodiment, the hologram recording layer 2 and the light transmitting material 3 are a holographic test plate 8E75HD manufactured by Agfargewald.
NAH was used as the adhesive layer 8, Canadian balsam manufactured by Junsei Chemical Co., Ltd., the matte light-transmitting material 9 was ground glass polished with a lathe having a thickness of 3 mm, and the light-absorbing material 10 was black lacquer spray.

することにより、不要な干渉縞のない回折格子を得るこ
とができた。A diffraction grating was recorded on the hologram recording layer 2 by injecting parallel light from the hologram recording material from opposite directions at an angle of 10 ° with respect to the normal using a helium neon laser. Excess light that has passed through the hologram recording layer 2 and the light transmitting material 3 is
Since the light is reflected at the interface of the light absorbing member 10 or is scattered and reflected by the presence of the matted portion, unnecessary interference does not occur. By actually developing with a Kodak D19 developer, a diffraction grating free of unnecessary interference fringes could be obtained.

マット加工しているが、必ずしも両面である必要はな
く、どちらか一方の面がマット加工してあれば光吸収性
材料10との界面で反射した光は散乱されるので、不要な
干渉縞を生ずることはない。In the above embodiment, both surfaces of the light-transmitting material 9 are matted. However, it is not always necessary that both surfaces be matted. Since the light reflected by the light source is scattered, unnecessary interference fringes do not occur.
また、マット加工は光透過性材料９でなく、光吸収性

となる。When the light-transmitting material 9 and the light-absorbing material 10 are bonded by the adhesive layer 8, if air enters the interface and bubbles are generated, reflection at that portion becomes a problem, but an adhesive made of a liquid is used. This can prevent bubbles from being generated. Further, by selecting the type of liquid or mixing several types of liquids, it becomes easy to make the refractive indices coincide with those of the light transmitting materials 3 and 9.

させることが可能となる。As described above, according to the present invention, since a material having at least one surface matted is used as a part of the hologram recording material, reflected light of extra light transmitted through the recording layer is irregularly reflected, thereby causing interference fringes. Therefore, it is possible to improve the image quality of the reproduced image.
