  • Patent number: 6522463
    Abstract: The infrared absorption filter of the present invention has a transmittance of not higher than 30% in the near-infrared region in the wavelength range of 800 to 1100 nm; a difference of 10% or less between a maximum value and a minimum value of transmittance in the visible light region in the wavelength range of 450 to 650 nm; and a transmittance of not lower than 50% at a wavelength of 550 nm, the filter being so excellent in environmental stability that after being left to stand in the air atmosphere at a temperature of 60° C. and a humidity of 95% for 1000 hours, the filter can maintain said spectral property in said range. Consequently, when used for a plasma display or the like, the filter can absorb the unwanted infrared rays radiated from the display, resulting in preventing erroneous operation of a remote control using infrared radiation even in such a high-temperature and high-humidity environment.

  • Patent number: 5856017
    Abstract: The present invention provides a gas barrier film including a plastic film and a thin film which is made of a composition containing an oxide as a main component and is formed on at least one surface of the plastic film. A specific gravity of the thin film is 55% or more and 100% or less of a specific gravity of the oxide in the form of a crystal generally present at room temperature and under atmospheric pressure. Thus, the invention provides a gas barrier film having an excellent gas barrier and retort properties and bending resistance; a gas barrier film suitably used in a wrapping material for dried food, liquid food or food containing liquids, frozen food and retort food; a gas barrier film that can be used in an electronic oven, can be sterilized by micro waves and can contain a free-oxygen absorber; a gas barrier film suitably used in a paper carton, a tube, a lid and the like; and a gas barrier film suitably used for cutting off gas for industrial use.

  • Patent number: 5567744
    Abstract: The present invention is concerned with a high water-absorbent resin composition, produced by forming a composite by fusing or fixing a thermoplastic resin onto a surface of a high water-absorbent resin via an adhesive binder or directly, wherein the composition comprises from 1 to 100 parts by weight of the thermoplastic resin, based on 100 parts by weight of the high water-absorbent resin.When the high water-absorbent resin composition of the present invention is used, it is possible to securely adhere a high water-absorbent resin to a fibrous base material, so that a water-absorbent material which stably retains the high water-absorbent resin even after absorbing water can be obtained. Accordingly, the base materials, such as fibrous base materials, can retain more amount of high water-absorbent resin than those of conventional water-absorbent materials.
