Abstract
Electronic articles such as, for example, electroluminescent lamps useful for displays and method of making the same are provided. The electronic articles include a substrate, a conductive element adjacent to the substrate, a high dielectric composite adjacent to the conductive element and an electrically-active layer adjacent to at least a portion of the high dielectric composite. The high dielectric composite includes a polymeric binder and from 1 to 80 volume percent of filler retained in the binder. The filler comprises particles that include an electrically-conducting layer and an insulating layer substantially surrounding the electrically-conducting layer. In some embodiments the binder includes a pressure-sensitive adhesive and the composite has adhesive properties.
