Abstract
A multi-layer conductive article and method of making same wherein the article has a first layer of an organic polymer having a volume resistivity of between about 10.sup.7 and 10.sup.12 ohm-cm, a second layer, preferably in direct physical and electrical contact with the first layer of a conductive polyurethane having a surface resistance on the order of 100 to 900 ohms/square and a third layer in direct physical and electrical contact with the second layer of an organic polymer having a volume resistivity of 10.sup.7 to 10.sup.12 ohm-cm so that the article is capable of dissipating static electric charges which are impressed thereupon. The first and third layers are preferably formed of polyvinyl chloride, while the third layer can be expanded to a foam. Also, the article can be laminated to a fabric sheet to form a conductive fabric.
