Abstract:

A transparent static dissipative adhesive tape is disclosed. The tape comprises a transparent polymer substrate having opposed first and second surfaces, a transparent static dissipative coating on the first surface of the substrate, and a transparent static dissipative adhesive coating on the second surface of the substrate. The adhesive coating comprises a transparent conductive layer on the second surface formed of conductive particles in a polymer matrix, and a transparent adhesive layer without any conductive particles over the conductive layer. The exposed surface of the adhesive layer exhibits conductivity substantially the same as the conductivity of the underlying conductive layer.
