    摘要： The present invention provides a method for storing holographic data comprising providing an optically transparent substrate comprising a photochemically active dye and a photo-acid generator; irradiating the optically transparent substrate with a holographic interference pattern, wherein the pattern has a first wavelength and an intensity both sufficient to convert, within a volume element of the substrate, at least some of the photochemically active dye into a photo-product, producing within the irradiated volume element concentration variations of the photo-product corresponding to the holographic interference pattern, thereby producing a first optically readable datum corresponding to the volume element; and irradiating the optically transparent substrate at a second wavelength and intensity sufficient to activate the photo-acid generator to stabilize the optically readable datum.

    摘要： A method of making a holographic data storage medium is provided. The method comprises: (a) providing an optically transparent substrate comprising at least one photochemically active dye; and (b) irradiating the optically transparent substrate at least one wavelength at which the optically transparent substrate has an absorbance in a range from about 0.1 to 1, to produce a modified optically transparent substrate comprising at least one optically readable datum and at least one photo-product of the photochemically active dye. The at least one wavelength is in a range from about 300 nanometers to about 800 nanometers. The optically transparent substrate is at least 100 micrometers thick, and comprises the photochemically active dye in an amount corresponding to from about 0.1 to about 10 weight percent based on a total weight of the optically transparent substrate.

    摘要： A process for preparing a polyestercarbonate copolymer which is nearly devoid of diaryl-carbonates and that exhibits a glass transition temperature lower than bisphenol-A carbonate homopolymer, and that shows improved processability is herein described. The desired lower Tg and improved flow can be achieved by the polycondensation of a dihydric phenol and aliphatic dicarboxylic acid. The condensate is polymerized with a carbonate forming reagent.
