Abstract
The present invention provides a transparent conductor comprising a successive lamination of a support, a conductive particle layer containing a conductive particle and a first binder, and a conductive film layer containing a bead and a second binder; wherein a surface of the conductive film layer opposite from the conductive particle layer is rough.
Claims12
A transparent conductor comprising a successive lamination of:
- a support;
- a conductive particle layer containing a conductive particle and a first binder, the conductive particle being fixed by curing the first binder so as to form the conductive particle layer;
- and
- a conductive film layer containing a bead and a second binder, the bead being fixed by curing the second binder so as to form the conductive film layer, wherein
- a surface of the conductive film layer opposite from the conductive particle layer is rough,
- the bead comprises a resin,
- the first binder comprises at least one of an acrylic resin and an epoxy resin, and
- the second binder comprises at least one of polyacetylene, polypyrrole, polythiophene, polyphenylenevinylene, polyphenylene, polysilane, polyfluorene and polyaniline.
