  • 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.
