Publication number: 20130011664Abstract: A molded oxide product of the present invention contains an oxide region and an organic cross-linked region and has at least a surface layer formed of an inorganic glassy material. The molded oxide product can combine both organic and inorganic advantages such as good workability of organic materials and high weather resistance, heat resistance and hardness of inorganic materials. The molded oxide product can be produced through the following steps: step A for preparing a precursor R2-M-O-M? having a polymerizable functional group-containing organic group R2 and a M-O-M? bond; step B for applying an application liquid containing the precursor; step C for hardening the application liquid by photocuring and/or thermosetting; and step D for performing oxidation treatment on at least a surface layer of the hardened product in such a manner as to convert at least the surface layer of the hardened product to be of inorganic glassy material.Type: ApplicationFiled: March 25, 2011Publication date: January 10, 2013Applicant: Central Glass Company, LimitedInventors: Masahide Takahashi, Rie Ihara

Patent number: 8343691Abstract: The present invention provides a hologram recording material which is not required to be subjected to pre-exposure treatment at the time of recording, attains high refractive index change, high sensitivity, low scattering, environment resistance, durability, low dimensional change, and high multiplicity, and is suitable for volume hologram recording. Also, the present invention provides a hologram recording medium. A hologram recording material comprising a matrix material having a softening temperature of 50° C. or higher, and a photopolymerizable monomer which is in a liquid phase state at room temperature. The matrix material is preferably contained in an amount of 50% by weight or more and 90% by weight or less of the whole of the hologram recording material. A softening temperature of the hologram recording material is preferably 0° C. or higher.Type: GrantFiled: April 25, 2005Date of Patent: January 1, 2013Assignee: TDK CorporationInventors: Tetsuro Mizushima, Jiro Yoshinari, Takuya Tsukagoshi, Hideaki Miura, Hideki Sunohara, Rie Ihara
