本発明はリップマンホログラムの再生色を赤方ないし貴

法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hologram in which the reproduced color of a Lippmann hologram is shifted from red to black and a method for producing the same.

おいても立体感があるため、カラーホログラムとしては
主流となってきている。Conventionally, rainbow holograms are known, in which the color is determined by the angle of the object beam and the reference beam, and a color hologram is created by multiple exposure with red (R), green (G), and blue (B). , the color changes and it is not recognized as color.
Since there is a drawback that the quality is not sufficient, R. Using three GSB laser beams, the object beam and reference beam are irradiated from opposite directions to form interference fringes in the depth direction of the recording material, and three (color) Lippmann holograms are projected and superimposed. A color Lippmann hologram has been proposed. Color Lippmann holograms have wavelength selectivity, red can be recognized as red no matter what angle you look at, and they have a three-dimensional effect both vertically and horizontally, so they have become mainstream as color holograms. There is.

８ｎｍ）、縁（Ａｒ ： ５ １ ４ｎｍ）赤（Ｈｅ−
Ｈｅ ： ６ ３ ３ｎｍ）等ノレーサーニヨッテ限定
サれてしまうという問題点があった。Incidentally, the Lippmann hologram has the property of reflecting and reproducing only light of a specific wavelength, but the wavelength depends on the interval of interference fringes recorded in the Lippmann hologram layer. The spacing of these interference fringes is determined by the laser wavelength during hologram recording, the Rayey light interference angle, the degree of shrinkage of the Lippmann hologram layer during development, etc., but generally the reproduction wavelength of this Lippmann hologram is the same as the laser wavelength during recording. There are many cases. Therefore, the reproduced color is blue (Ar: 48
8nm), edge (Ar: 514nm) red (He-
He: 6 3 3 nm), etc., had the problem that it was limited to Niyotte.

ようになってきているが、これらの方法の有効なホログ
ラム記録材は限られており、銀塩乳剤等親水性ポリマー
を含む系に限定されていた。Therefore, there is a method of swelling or shrinking the Lippmann hologram layer using triethanolamine, D-sorbitol aqueous solution, etc. to change the spacing of interference fringes and shifting the regeneration liquid length in an arbitrary direction to obtain various reproduced colors. Although these methods are increasingly being used, the effective hologram recording materials for these methods are limited, and are limited to systems containing hydrophilic polymers such as silver salt emulsions.

The purpose is to

マンホログラム作成方法を特徴とするものである。As a result of intensive study to solve the above problems, we have arrived at the idea that in order to shift the reproduction wavelength of a Lippmann hologram, it is sufficient to change the interval of interference fringes in the Lippmann hologram layer and maintain that state. . That is, the present invention provides a Lippmann hologram layer made of a lipophilic polymer that has been subjected to exposure and phenomenon treatment, has been uniformly coated with an organic solvent containing a non-volatile component, and has been swollen or shrunk and dried; A method for producing a Lippmann hologram is characterized by the steps of: and a phenomenon treatment step; and a step of uniformly applying an organic solvent containing a non-volatile component, and swelling or shrinking and drying a Lippmann hologram layer made of a lipophilic polymer. .

く、間隔が広がれば再生波長は長波長側ヘシフトし、狭
まれば短波長側にシフトする。To shift the reproduction wavelength of the Lippmann hologram,
It is sufficient to change the interval between the interference fringes in the Lippmann hologram layer; if the interval is widened, the reproduction wavelength shifts to the longer wavelength side, and if it is narrowed, the reproduced wavelength is shifted to the shorter wavelength side.

ができる。That is, when a non-volatile compound is mixed into an organic solvent and applied uniformly to a Lippmann hologram layer made of a lipophilic polymer, the non-volatile compound penetrates into the Lippmann hologram layer at the same time as the Lippmann hologram layer expands and contracts uniformly. Since the expanded or contracted state in the Lippmann hologram layer is maintained even after the organic solvent is removed by drying, interference fringes at arbitrary intervals can be recorded.

Place a 3-weight photosensitive layer on a glass plate.
It was coated to a thickness of 0 μm, and a Lippmann hologram (diffraction grating) was photographed using the optical system shown in FIG. That is, 48
An 8 nm Ar laser is divided into two by a half mirror 2, diffused through a mirror 3 and a spatial filter 4, and irradiated from both sides of a photosensitive material plate 5 to produce a Lippmann hologram. After exposure, development was performed in an alcohol bath, a toluene bath, and a pentane bath, and a purple reproduced color was obtained. The following composition was applied on the resulting Lippmann hologram layer: n-butyl phthalate 5 parts by weight toluene
5 parts by weight bentane
When 50 parts by weight of the swelling liquid was coated and rapidly dried, the regenerated color shifted to green.

Even after the compound enters the Lippmann hologram layer and the organic solvent is removed by drying, the expansion or contraction state in the Lippmann hologram layer is maintained, so the reproduction wavelength can be arbitrarily shifted to obtain any reproduction color. becomes possible.
