    摘要: A photosensitive film for holographic recording and its production method thereof are disclosed. The film comprises a base film, a buffer layer coated on one side of the base film, a photosensitive polymer coating layer formed by applying a photosensitive coating on the other side of the buffer layer, and a surface protective film covering the surface of the photosensitive polymer coating layer. Interference fringe patterns of a holographic image or an amphichronic graph are recorded in the photosensitive polymer coating layer. The film according to the present invention is a photosensitive material composed of two polymers of different refractive indexes, when coherent light beams intersect in its recording medium and produce an interference fringe pattern in the medium, monomers therein are excited accordingly and undergo free radical polymerization, thereby forming a hologram.

    摘要: An efficient and commercially-viable method for the stereoselective transformation of a diol to an alcohol is disclosed. The present method is particularly well-suited for the preparation of the unnatural D-isomer of malic acid or its derivatives from the abundant naturally occurring L-tartaric acid or derivatives thereof.
