  • Patent number: 7956287
    Abstract: A touch panel-use transparent conductive molded product having a conductive layer excellent in wear resistance and flexing resistance, small in surface resistivity change when the touch panel is in use, and free from a change in transmitted light hue, and a touch panel using it. The touch panel-use transparent conductive molded product comprises a fine-conductive-fibers (4)-containing, transparent conductive layer (12) formed on at least one surface of a transparent substrate (11), and the touch panel uses the above transparent conductive molded product as an electrode. The fine conductive fibers in the transparent conductive layer (12) are dispersed without being aggregated, and touch each other while being dispersed with each of them separated from each other or each bundle of several fibers separated from each other. Therefore, it is possible to control a surface resistivity to 104?/? or smaller, and a conductive layer light beam transmittance at a wavelength of 550 nm to 75% or larger.

  • Publication number: 20080029292
    Abstract: There are provided a transparent conductive formed article for a touch panel, having a conductive layer which is excellent in abrasion resistance and elasticity, shows little change in surface resistivity at the time of the use of a touch panel, and does not change hues of the transmitting light, and a touch panel that use the same. The transparent conductive formed article for a touch panel is prepared by forming a transparent conductive layer 12 comprising ultra fine conductive fibers 4 on at least one side of a transparent substrate 11, and the touch panel is prepared using the aforementioned transparent conductive formed article as an electrode. The ultra fine conductive fibers of the transparent conductive layer 12 are dispersed without aggregation and dispersed and contacted with one another in a state in which said fibers are separated one by one or in a state in which a bundle formed by the gathering of two or more fibers is separated from other bundles.
