Problems solved by technology

[0019] However, since it is difficult for oxygen to permeate uniformly in the medium, the effect may be insufficient or the life of the medium may be shortened by the permeated oxygen or moisture, so it cannot be said that it can fully obtain the expected effect.

Embodiment 1

[0243] Weigh 7.892g of the compound added with 2-ethylhexanol in the hexamethylene diisocyanate polymer, p-cumylphenol EO modified Acrylate 1.667g, (η5-2,4-cyclopentadiene-1-yl)-bis(2,6-difluoro-3-(1H-pyrrole-1-yl)-phenyl)titanium 0.083 g. Put 0.0083 g of terpinolene into sample bottle 1, and stir until each component is dissolved.

[0244] Next, 7.108 g of polycaprolactone triol with a molecular weight of 500 and 0.003 g of dioctyltin dilaurate were weighed into sample bottle 2, and stirred until each component was dissolved.

[0245] Then, the sample bottles 1 and 2 were put into a bell-shaped sintering furnace, and after 3 hours of vacuum degassing, the liquids in the sample bottles 1 and 2 were mixed together and stirred to mix, and the bell-shaped sintering furnace was vacuum-degassed for several minutes.

[0246] Next, on an aluminum-deposited glass plate (on the side on which the aluminum is deposited) provided with Teflon (registered trademark) sheets with a thicknes...

Embodiment 2

[0248] Same as Example 1, weigh hexamethylene diisocyanate 4.743g, tribromophenyl acrylate 1.667g, bis(η 5-2,4-cyclopentadiene-1-yl)-bis(2,6 0.083 g of -difluoro-3-(1H-pyrrole-1-yl)-phenyl)titanium and 0.0083 g of terpinolene were put into sample bottle 1, and stirred until each component was dissolved.

[0249] Also, 10.257 g of polycaprolactone triol with a molecular weight of 500 and 0.003 g of dioctyltin dilaurate were weighed into sample bottle 2, and stirred until each component was dissolved.

[0250] Then, the same operation as in Example 1 was performed to prepare a recording layer.

Embodiment 3

[0252] Same as Example 1, weigh 7.892g of the compound added with 2-ethylhexanol in the hexamethylene diisocyanate polymer, 1.667g of tribromophenyl acrylate, bis(η5-2,4-cyclo Pentadiene-1-yl)-bis(2,6-difluoro-3-(1H-pyrrole-1-yl)-phenyl)titanium 0.083g, γ-terpinene 0.0083g into the sample bottle 1, stir until all ingredients are dissolved.

[0253] Also, 7.108 g of polycaprolactone triol with a molecular weight of 500 and 0.003 g of dioctyltin dilaurate were weighed into sample bottle 2, and stirred until each component was dissolved.

[0254] Then, the same operation as in Example 1 was performed to prepare a recording layer.

Abstract

This invention provides, for example, a highly stable and reliable volume hologram optical recording medium which can suppress an intensity variation, for example, in diffraction efficiency after signal recording and can stably develop a high S / N ratio. The volume hologram optical recording medium comprises a recording layer containing at least one compound selected from compounds (A1) having a terpenoid skeleton, compounds (A2) represented by general formula (I), and cyclic or noncyclic compounds (A3) having at least two double bonds two of which double bonds are relatively located at 1,4-position, wherein R and R each independently represent an organic group having 1 to 20 carbon atoms, provided that R and R may combine to form a cyclic structure.

Description

technical field [0001] The present invention relates to a volume holographic optical recording medium, etc., and more specifically relates to such a volume holographic optical recording medium, etc., which can record three-dimensional information through the irradiation of multiple beams of coherent light. Background technique [0002] In recent years, in order to increase the capacity and density of optical recording media, people are developing a volume holographic optical recording medium, which makes the refraction of the recording layer according to the distribution of light intensity caused by light interference. The rate changes and the information is holographically recorded. [0003] The general principles of holographic production are described in several documents or professional books (see Non-Patent Document 1). According to these documents, an object to be recorded is irradiated with one of two coherent laser beams, and a photosensitive hologram recording mate...
