Embodiment 1

[0127] Using phenyltrimethoxysilane and titanium dioxide sol, a hologram recording material was produced by the sol-gel method in the following procedure.

[0128] (Preparation of matrix material)

[0129] To 7.8 g of phenyltrimethoxysilane, 20 ml of isopropanol was added. Next, a solution comprising 1.0 ml of water, 0.1 ml of 1N aqueous hydrochloric acid solution, and 2 ml of isopropanol was added dropwise to the alkoxide solution at room temperature while stirring, and then heated to reflux for 1 hour to perform a hydrolysis reaction.

[0130] After cooling the solution to room temperature, TiO was added to the solution 2 40 g of sol (manufactured by Catalyst Kasei Kogyo Co., Ltd., dispersed in isopropanol, non-volatile matter concentration: 20.5% by weight) was further stirred at room temperature for 1 hour. The mass ratio of silane oxide / titanium-containing oxide fine particles=0.95 / 1.0. Thus a sol solution was obtained.

[0131] (photopolymerizable compound)

Abstract

The present invention provides a hologram recording material which is suitable for volume hologram record and can attain high refractive index change, flexibility, high sensitivity, low scattering, environment resistance, durability, low dimensional change (low shrinkage) and high multiplicity in holographic memory record using not only a green laser but also a blue laser; and provides a hologramrecording medium having a hologram recording layer comprising the hologram recording material. A hologram recording material comprising a metal oxide matrix and a photopolymerizable compound, whereinthe metal oxide matrix comprises at least Si and Ti as metallic elements, and Ti originates from titanium-containing oxide fine particles. A hologram recording medium ( 11 ) having the hologram recording layer ( 21 ) comprising the hologram recording material.

Description

technical field [0001] The present invention relates to a hologram recording material suitable for volume-type hologram recording, and a hologram recording medium having a hologram recording layer composed of the hologram recording material. In particular, the present invention relates to a hologram recording material suitable for recording / reproducing not only by a green laser but also a blue laser, and a hologram recording medium having a hologram recording layer composed of the hologram recording material. Background technique [0002] Research and development of holographic memory is underway as a recording technology that enables large-capacity, high-speed transfer. Oplus E, Vol. 25, No. 4, 385-390 (2003) describes the basic configuration and future prospects of the holographic memory. [0003] The properties required for a hologram recording material include, for example, high refractive index change during recording, high sensitivity, low scattering, environmental re...
