Abstract
The present invention discloses an ultraviolet light curable transparent conductive composition and method for making such a composition that may be used to produce a transparent conductive coating on a suitable substrate. These coatings may be used in such applications as touch screens, membrane switches, TV screens, and VCRs. The disclosed composition does not contain any significant amount of volatile organic solvents that do not become incorporated in the active layer after curing.
