A hologram is an interference pattern of coherent light from a laser or the like recorded on a photosensitive material or the like. These are used for three-dimensional image creation, optical elements, and the like. The characteristics required for materials for hologram recording are He-Ne (wavelength 633 nm), Ar (wavelength 515 nm,
488 nm) He-Cd (wavelength: 442 nm) and other laser beams are sensitive to laser light, the hologram has high diffraction efficiency, high resolution, and easy development processing. To date, as practical photosensitive materials, dichromate gelatin and bleached silver salt dry plates used in ordinary photographic materials are known. However, silver halide has high sensitivity,
Further, although dichromate gelatin has a high diffraction efficiency, it has the disadvantage that the process for producing a hologram is complicated, and in particular requires a wet development and fixing process.

る。 As a method to overcome this problem, a method using a photopolymerizable recording material mainly composed of a mixture of two types of monomers was proposed (W.J. Tomlinson et al., Appl.
Opt., vol 15, 534 (1976). That is, by photopolymerizing a portion of the interference pattern with a large amount of light, the refractive index of that portion is modulated and recorded.

However, in the conventional materials described above, the portion where the amount of light is low remains as unreacted monomer, and it is necessary to stabilize recording by exposing the entire surface to ultraviolet light or the like. In addition, it had drawbacks such as insufficient practical performance such as laser sensitivity, diffraction efficiency, and resolution.

It wasn't something. Furthermore, the flow of the composition during hologram recording has made recording impossible or hindered recording with good reproducibility.

As a result of intensive research into the composition of photopolymerizable materials containing multiple types of monomers with significantly different photoreactivity and refractive index, the present inventors found that They discovered that when a group-containing monomer and a bromine-containing aromatic monomer are combined, a hologram with good physical properties can be obtained by a simple exposure operation.Furthermore, this recording material is fixed by heat treatment, and coherent light is emitted. It has been found that good results can be obtained by irradiation.

1.6と高い。 In the hologram recording material of the present invention, allyl diglycol carbonate used as a main monomer contains two allyl groups in the molecule and functions as a low-reactivity monomer. The refractive index of a resin obtained by polymerizing this alone is approximately 1.5. In addition, 2,2-bis[3,5-dibromo-4-(2-methacryloyloxyethoxy)phenyl]propane, which is used as an adjuvant monomer, has two methacrylic groups at the end of the molecule and is highly photopolymerizable. Acts as a highly reactive monomer. The refractive index of the homopolymerized resin is approximately
It is high at 1.6.

A material that absorbs laser light and generates radicals, such as m), is used.

Examples include benzyl-Mihiraketone, benzyl-acridine yellow, and halogen compound-merocyanine. The amount of radical generator and dye added is 0.5 to 0.5 to the total amount of monomer.

A small amount of organic solvent may also be added for the same purpose. For example, toluene, xylene, acetone, methyl ethyl ketone, etc. are used in an amount of about 0.5 to 20 wt% based on the total amount of monomers.

イルムなど、透明性の良いものが使用される。 As the surface material between which the recording material is held, a material with good transparency, such as a glass plate, a plastic plate, or a plastic film, is used.

ので、ここでの説明は省略する。 The heat treatment is performed by injecting the photopolymerizable composition between the two surface materials and then leaving it in an oven set at 50 to 200°C for several minutes to several tens of minutes. Even when taken out and returned to room temperature, monomer crystals do not precipitate and the surface material does not shift. Next, this dry plate is used to fabricate a hologram, but since it can be done in the same manner as a generally well-known method, the explanation here will be omitted.

When the recording material of the present invention is exposed to an interference pattern, the highly reactive monomer polymerizes first in areas exposed to a large amount of light, causing volumetric contraction. Then, due to diffusion, the polymerization progresses further with the highly reactive monomers moving to areas where the amount of light is high and the low reactivity monomers moving to areas where the amount of light is low. On the other hand, polymerization progresses even in areas where the amount of light is low, although there is a slight delay compared to areas where the amount of light is high. This is brought about by the fact that the molecule of allyl diglycol carbonate, which is present as a low-reactivity monomer, contains two allyl groups and by the improvement in polymerizability in the coexistence of a small amount of bromine-containing aromatic monomer. As a result, areas with a large amount of light give a polymer with a high refractive index, and conversely, areas with a low amount of light give a polymer composition with a lower refractive index, resulting in an interference pattern that modulates the refractive index as a reflection of the composition distribution depending on the amount of light. This enables real-time and stable recording.

果、回折効率の向上がもたらされる。 Further, when the entire photopolymerizable composition covered with the surface material is heat-treated by the recording method of the present invention, the composition is thermally polymerized and reaches a highly viscous state or almost a solid state. As a result, the surface material is fixed to such an extent that it does not move or peel off. The dry plate treated in this way still has sufficient photopolymerization performance, so when information is written by irradiating it with coherent light, a microscopic movement of low-reactivity monomers and high-reactivity monomers occurs. occurs and refractive index modulation recording is performed. Moreover, the composition as a whole does not flow significantly and the thickness of the recording layer is maintained uniformly by the surface material, resulting in an improvement in diffraction efficiency.

9g of hydroxypropyl acrylate, benzyl
A recording material "B" was prepared consisting of 1.8 g of mihiraketone and 0.6 g of mihiraketone. These "A" and "B" were injected between two glass plates of 50 x 60 x 1.5 mm so that the thickness was several μm, and in an oven at 150 degrees, A for 15 minutes and B for 10 minutes. A dry plate was prepared by heat treatment for a minute. These dry plates did not precipitate monomer crystals during storage, the glass did not shift during handling, and they were easy to carry. Furthermore, the composition layer maintained a constant thickness. next,
An interference pattern (200
mJ/cm 2 ) and applied it to a dry plate, an interference pattern could be recorded with good reproducibility by photopolymerization in a few seconds to a few minutes with just this operation. In either case, there is no need for developing or fixing operations, and the low-reactivity monomer portion is also solidified, resulting in a stable hologram (diffraction efficiency of approximately 40 for both A and B).
%) was completed. It was confirmed that this recording was performed only by modulation of the refractive index rather than by the unevenness of the film, and that it was a transparent hologram with almost no absorption in the visible region.
