1. An optical display filter comprising:

  • a transparent polymeric substrate;

    a multi-layer construction adjacent to the substrate, the construction consisting essentially of;

    an electrically-conductive layer having a first surface and a second surface;

    a discontinuous nucleation layer in contact with the first surface; and

    a barrier layer in contact with the second surface, anda transparent dielectric layer adjacent to the construction; and

    a basecoat polymer layer between the substrate and the multi-layer construction, wherein the transparent dielectric layer comprises an organic polymer having a refractive index greater than about 1.49.
