    Abstract: It is disclosed a transparent conductive multi-layer structure which comprises a substrate overlaid, desirably interposed by a support, with a conductive layer containing fine conductive particles, preferably the fine particles of indium-tin oxide (ITO), said multi-layer structure having a surface resistance of 10-103?/? and a visible light transmittance of at least 70%. A process for producing this structure is also disclosed. The present invention can produce transparent conductive multi-layer structures by utilizing a coating method which retains the advantages of its easiness of forming large-area conductive films, simplification of apparatus, high productivity and low manufacturing cost, by firstly obtaining a transparent conductive film that has low enough surface resistance to give high conductivity while exhibiting satisfactory transparency, and then applying the transparent conductive film to a glass or resin panel, etc.

  • Patent number: 7452435
    Abstract: A functional film of the invention includes a microparticulate-containing layer containing functional microparticulates. The microparticulate-containing layer inhibits the occurrence of cracks even when drawn 10%. When the functional film includes a microparticulate-containing layer containing conductive microparticulates, the microparticulate-containing layer exhibits a surface resistivity after drawn 10% which is at most 10 times greater than the surface resistivity prior to drawing. The invention thus implements a functional film which is unsusceptible to reduction or loss of its function due to deformation.
