Latest Patents
Yasushi Ohe's latest patents include innovative formulations for photosensitive recording materials. One of his patents describes a photosensitive recording material that comprises an alicyclic, solvent-soluble, thermosetting epoxy oligomer capable of cationic polymerization. This oligomer is combined with an aliphatic monomer that has at least one ethylenically unsaturated bond, which is liquid at normal temperature and pressure. The monomer has a boiling point of 100°C or above and is capable of radical polymerization. The patent also details a photoinitiator that generates both radical species and Brønsted or Lewis acids upon exposure to actinic radiation. This formulation is particularly effective for producing volume type phase holograms with superior diffraction efficiency, transparency, and weatherability.
Another patent by Ohe focuses on a similar photosensitive recording material, emphasizing the importance of the thermosetting epoxy oligomer and the aliphatic monomer. The use of this material is also aimed at achieving high-quality volume type phase holograms that exhibit excellent thermal resistance and chemical stability.
