  • Oxygen-absorbing material
    Patent number: 6689437
    Abstract: An oxygen-absorbing material including a transition metal compound and one or more thermoplastic resins, when used for a molded product such as container, exhibits excellent gas-barrier and oxygen-absorbing properties. The material absorbs oxygen from contents and blocks oxygen from entering so that the contents can be maintained in an oxygen-free state for a long period of time. An excellent oxygen-absorbing property is achieved by an amino group content of 20 mmol/kg or lower in at least one thermoplastic resin and by lowering the crystallinity of the thermoplastic resin.

  • Transparent conductive film, transparent conductive sheet and touchpanel
    Patent number: 6603085
    Abstract: A transparent conductive film has a cured layer mainly containing a curable resin and a transparent conductive thin film successively layered on a transparent plastic film base. The transparent conductive film is characterized in that it has 3-200 protrusions over the surface of the transparent conductive thin film per 100 &mgr;m2, each having a diameter of 0.05-3.0 &mgr;m and a height of 0.005-2.00 &mgr;m. The transparent conductive film is characterized in that a volatile component amount contained in the transparent conductive film is at most 30 Pa.
